The parser currently has two DeclNameRef-parsing functions,
parseUnqualifiedDeclName()
andparseUnqualifiedDeclBaseName()
, which take four undifferentiatedbool
s to control their behavior. I will soon need yet another flag, so this is getting a bit out of hand.This PR replaces them with a
parseDeclNameRef()
function and a flag enum to control these behaviors. This should improve the readability of existing code and help accommodate future flag additions.
