Summary: Default values of function arguments are ignored when

void foo(Fn)(Fn fn)
{
fn();
}
void bar(int i = 22) {
writeln("bar ", i);
}
void bam(int i) {
writeln("bam ", i);
}
void baz() {
foo(&bar);
foo(&bam);
}
This code compiles while it should not. You cannot call bam() without any
arguments. If you switch the instantiations and call foo(&bam) first - it does
not compile.
pragma(msg, typeof(&bar).stringof);
pragma(msg, typeof(&bam).stringof);
outputs
void function(int i = 22)
void function(int i)
But it is not respected by the template.
