           Summary: Types can't be inferred from template argument types

The following program fails for me (DMD 2.052):

import std.array, std.container;

template func(T) {
    alias void function(T) func;
}

void G(uint x) {
}

void f(T)(func!T g) { // Won't work, except with (*)
// void f(T)(void function(T) g) {
}

void main() {
    f(&G);
    // f!uint(&G); // (*)
}

With the explicit "void function(T) g" in the argument specification, it works.
Or, if f!uint is specified explicitly. The problem seems to be inferring the
type T "through" the template func().
