abstract class `AttribDeclaration`: dmd.dsymbol.Dsymbol;
  static Scope* `createNewScope`(Scope* `sc`, StorageClass `stc`, LINK `linkage`, CPPMANGLE `cppmangle`, Prot `protection`, int `explicitProtection`, AlignDeclaration `aligndecl`, PINLINE `inlining`);
    Create a new scope if one or more given attributes are different from the sc's. If the returned scope != sc, the caller should pop the scope after it used.
  Scope* `newScope`(Scope* `sc`);
    A hook point to supply scope for members. addMember, setScope, importAll, semantic, semantic2 and semantic3 will use this.
  final void `addLocalClass`(ClassDeclarations* `aclasses`);
class `StorageClassDeclaration`: dmd.attrib.AttribDeclaration;
class `DeprecatedDeclaration`: dmd.attrib.StorageClassDeclaration;
  Scope* `newScope`(Scope* `sc`);
    Provides a new scope with STC.deprecated_ and Scope.depdecl set
    Calls StorageClassDeclaration.`newScope` (as it must be called or copied in any function overriding `newScope`), then set the Scope's depdecl.
    Returns:
    Always a new scope, to use for this DeprecatedDeclaration's members.
class `LinkDeclaration`: dmd.attrib.AttribDeclaration;
class `CPPMangleDeclaration`: dmd.attrib.AttribDeclaration;
class `ProtDeclaration`: dmd.attrib.AttribDeclaration;
  this(ref const Loc `loc`, Prot `p`, Dsymbols* `decl`);
    Parameters:

    Loc `loc` | source location of attribute token
    Prot `p` | protection attribute data
    Dsymbols* `decl` | declarations which are affected by this protection attribute

  this(ref const Loc `loc`, Identifiers* `pkg_identifiers`, Dsymbols* `decl`);
    Parameters:

    Loc `loc` | source location of attribute token
    Identifiers* `pkg_identifiers` | list of identifiers for a qualified package name
    Dsymbols* `decl` | declarations which are affected by this protection attribute

class `AlignDeclaration`: dmd.attrib.AttribDeclaration;
class `AnonDeclaration`: dmd.attrib.AttribDeclaration;
class `PragmaDeclaration`: dmd.attrib.AttribDeclaration;
class `ConditionalDeclaration`: dmd.attrib.AttribDeclaration;
class `StaticIfDeclaration`: dmd.attrib.ConditionalDeclaration;
  Dsymbols* `include`(Scope* `sc`);
    Different from other AttribDeclaration subclasses, include() call requires the completion of addMember and setScope phases.
class `StaticForeachDeclaration`: dmd.attrib.AttribDeclaration;
  Static foreach at declaration scope, like: static foreach (i; [0, 1, 2]){ }
  StaticForeach `sfe`;
    contains static foreach expansion logic
  ScopeDsymbol `scopesym`;
    cached enclosing scope (mimics static if declaration)
  bool `onStack`;
    include can be called multiple times, but a static foreach should be expanded at most once. Achieved by caching the result of the first call. We need both cached and cache, because null is a valid value for cache.
class `ForwardingAttribDeclaration`: dmd.attrib.AttribDeclaration;
  Collection of declarations that stores foreach index variables in a local symbol table. Other symbols declared within are forwarded to another scope, like:
  static foreach (i; 0 .. 10) // loop variables for different indices do not conflict. { // this body is expanded into 10 ForwardingAttribDeclarations, where i has storage class STC.local mixin("enum x" ~ to!string(i) ~ " = i"); // ok, can access current loop variable }
  static foreach (i; 0.. 10) { pragma(msg, mixin("x" ~ to!string(i))); // ok, all 10 symbols are visible as they were forwarded to the global scope }
  static assert (!is(typeof(i))); // loop index variable is not visible outside of the static foreach loop
  A StaticForeachDeclaration generates one ForwardingAttribDeclaration for each expansion of its body. The AST of the ForwardingAttribDeclaration contains both the `static foreach variables and the respective copy of the static foreach` body. The functionality is achieved by using a ForwardingScopeDsymbol as the parent symbol for the generated declarations.
  Scope* `newScope`(Scope* `sc`);
    Use the ForwardingScopeDsymbol as the parent symbol for members.
  void `addMember`(Scope* `sc`, ScopeDsymbol `sds`);
    Lazily initializes the scope to forward to.
class `CompileDeclaration`: dmd.attrib.AttribDeclaration;
  Mixin declarations, like: mixin("int x"); https://dlang.org/spec/module.html#mixin-declaration
class `UserAttributeDeclaration`: dmd.attrib.AttribDeclaration;
  User defined attributes look like: @foo(args, ...) @(args, ...)
