Description

Sometimes no completions are displayed for template arguments. A couple of places I've identified are module and class/struct level, and function parameters.

Module/Class/struct-level variable:

struct Foo(T) {}

Foo!str <- No completions

Function parameters:

void bar(Foo!str <- No completions
