Source: access.d

bool `checkAccess`(AggregateDeclaration `ad`, Loc `loc`, Scope* `sc`, Dsymbol `smember`);
  Do access check for member of this class, this class being the type of the 'this' pointer used to access `smember`. Returns `true` if the member is not accessible.
bool `checkAccess`(Loc `loc`, Scope* `sc`, Expression `e`, Declaration `d`);
  Check access to `d` for expression `e`.`d` Returns `true` if the declaration is not accessible.
bool `checkAccess`(Loc `loc`, Scope* `sc`, Package `p`);
  Check access to package/module `p` from scope `sc`.
  Parameters:

  Loc `loc` | source location for issued error message
  Scope* `sc` | scope from which to access to a fully qualified package name
  Package `p` | the package/module to check access for

  Returns:
  `true` if the package is not accessible.
  Because a global symbol table tree is used for imported packages/modules, access to them needs to be checked based on the imports in the scope chain (see https://issues.dlang.org/show_bug.cgi?id=313).
bool `symbolIsVisible`(Module `mod`, Dsymbol `s`);
  Check whether symbols `s` is visible in `mod`.
  Parameters:

  Module `mod` | lookup origin
  Dsymbol `s` | symbol to check for visibility

  Returns:
  `true` if `s` is visible in `mod`
bool `symbolIsVisible`(Dsymbol `origin`, Dsymbol `s`);
  Same as above, but determines the lookup module from symbols `origin`.
bool `symbolIsVisible`(Scope* `sc`, Dsymbol `s`);
  Same as above but also checks for protected symbols visible from scope `sc`. Used for qualified name lookup.
  Parameters:

  Scope* `sc` | lookup scope
  Dsymbol `s` | symbol to check for visibility

  Returns:
  `true` if `s` is visible by origin
