StringExp `semanticString`(Scope* `sc`, Expression `exp`, const char* `s`);
  Resolve `exp` as a compile-time known string.
  Parameters:

  Scope* `sc` | scope
  Expression `exp` | Expression which expected as a string
  char* `s` | What the string is expected for, will be used in error diagnostic.

  Returns:
  String literal, or null if error happens.
Expression `resolveOpDollar`(Scope* `sc`, ArrayExp `ae`, Expression* `pe0`);
  Runs semantic on ae.arguments. Declares temporary variables if '$' was used.
Expression `resolveOpDollar`(Scope* `sc`, ArrayExp `ae`, IntervalExp `ie`, Expression* `pe0`);
  Runs semantic on se.lwr and se.upr. Declares a temporary variable if '$' was used.
bool `arrayExpressionSemantic`(Expressions* `exps`, Scope* `sc`, bool `preserveErrors` = false);
  Perform semantic() on an array of Expressions.
Expression `resolvePropertiesOnly`(Scope* `sc`, Expression `e1`);
  If e1 is a property function (template), resolve it.
Expression `resolve`(ref const Loc `loc`, Scope* `sc`, Dsymbol `s`, bool `hasOverloads`);
  Resolve a symbol `s` and wraps it in an expression object.
  Parameters:

  Loc `loc` | location of use of `s`
  Scope* `sc` | context
  Dsymbol `s` | symbol to resolve
  bool `hasOverloads` | applies if `s` represents a function. true means it's overloaded and will be resolved later, false means it's the exact function symbol.

  Returns:
  `s` turned into an expression, ErrorExp if an error occurred
Expression `trySemantic`(Expression `exp`, Scope* `sc`);
  Try to run semantic routines. If they fail, return NULL.
Expression `unaSemantic`(UnaExp `e`, Scope* `sc`);
  Helper function for easy error propagation. If error occurs, returns ErrorExp. Otherwise returns NULL.
Expression `binSemantic`(BinExp `e`, Scope* `sc`);
  Helper function for easy error propagation. If error occurs, returns ErrorExp. Otherwise returns NULL.
