--- Comment #1 from Iain Buclaw <ibuc...@gdcproject.org> --- Similar to issue 21992. While the rewrite could be handled by DeclarationExp semantic. There's no way to know that the original declaration had parenthesis around the variable name. e.g: If `e.declaration.type` resolves as a function declaration, how do we know whether the original code was `fn(p);` or `fn p;`? It's probably safer to first assume CallExp in CParser, as that's the most common usage of the ambiguous syntax. If `fn` is then found to be a type, rewrite it into a DeclarationExp. --
