I tagged this as enhancement but I consider it as borderline bug report:
struct Foo(T) { T x; }
void bar1(T)(Foo!T c) {}
alias F(T) = Foo!T;
void bar2(T)(F!T c) {} // line 4, error
void main() {
F!int x = Foo!int(1);
bar1(x); // OK
bar2(x); // line 8, error
}
dmd 2.064alpha:
test.d(8): Error: template test.bar2 does not match any function template declaration. Candidates are:
test.d(4): test.bar2(T)(F!T c)
test.d(8): Error: template test.bar2(T)(F!T c) cannot deduce template function from argument types !()(Foo!int)
Support for similar code is handy to use alias expressions to shorten code when the same complex type is used in many function signatures, like in bar2.
