class `Identifier`: dmd.root.rootobject.RootObject;
  nothrow this(const(char)* `name`, size_t `length`, int `value`);
    Construct an identifier from a D slice

    Note Since `name` needs to be \0 terminated for toChars, no slice overload is provided yet.

    Parameters:

    const(char)* `name` | the identifier name There must be '\0' at `name`[`length`].
    size_t `length` | the length of `name`, excluding the terminating '\0'
    int `value` | Identifier value (e.g. Id.unitTest) or TOK.identifier

  static nothrow Identifier `anonymous`();
    Sentinel for an anonymous identifier.
  static nothrow Identifier `generateIdWithLoc`(string `prefix`, ref const Loc `loc`);
    Generate deterministic named identifier based on a source location, such that the name is consistent across multiple compilations. A new unique name is generated. If the prefix+location is already in the stringtable, an extra suffix is added (starting the count at "1").
    Parameters:

    string `prefix` | first part of the identifier name.
    Loc `loc` | source location to use in the identifier name.

    Returns:
    Identifier (inside Identifier.idPool) with deterministic name based on the source location.
  static nothrow Identifier `idPool`(const(char)* `s`, uint `len`);
    Create an identifier in the string table.
  static nothrow bool `isValidIdentifier`(const(char)* `str`);
  static nothrow bool `isValidIdentifier`(const(char)[] `str`);
    Determine if string is a valid Identifier.
    Parameters:

    const(char)* `str` | string to check

    Returns:
    false for invalid
