q{} would suggest the argument is a string, right? Plus, why does 
deps have to be a template?

This is unnecessarily powerful.

I would prefer my @import alternative. If we make use of q{}, it 
would look fine too:

@import(q{std.file: File}) @import(q{std.range: isInputRange})
void foo(T)(File x) if (isInputRange!T);
