AST.Objects* parseTemplateArguments();
Parse template arguments.

Input: current token is opening '!'

Output: current token is one after closing ')'

AST.Objects* parseTemplateArgumentList();
Parse template argument list.

Input: current token is opening '(', or ',' for _traits

Parse a static assertion. Current token is 'static'.
AST.TypeQualified parseTypeof();
Parse typeof(expression). Current token is on the 'typeof'.
AST.Type parseVector();
Parse _vector(type). Current token is on the '_vector'.
LINK parseLinkage(AST.Identifiers** pidents, out CPPMANGLE cppmangle);

Parse: extern (linkage) extern (C++, namespaces) The parser is on the 'extern' token.

AST.Identifiers* parseQualifiedIdentifier(const(char)* entity);
Parse ident1.ident2.ident3
const(char)* entity what qualified identifier is expected to resolve into. Used only for better error message
array of identifiers with actual qualified one stored last

Parse a debug conditional
AST.Condition parseVersionCondition();
Parse a version conditional
AST.Condition parseStaticIfCondition();
static if (expression) body else body Current token is 'static'.
AST.Dsymbol parseCtor(PrefixAttributes!AST* pAttrs);
Parse a constructor definition: this(parameters) { body } or postblit: this(this) { body } or constructor template: this(templateparameters)(parameters) { body } Current token is 'this'.

Parse a static destructor definition: static ~this() { body } Current token is 'static'.
AST.Dsymbol parseSharedStaticCtor(PrefixAttributes!AST* pAttrs);
Parse a shared static constructor definition: shared static this() { body } Current token is 'shared'.
