i don't think that shadowing globals should always generate warning. i believe
that it's enough to generate warning only when there is possible UFCS
shadowing.

so:

import std.stdio;
void foo(int a) {
     writeln("it's a function! : ", a);
}
void main() {
     auto foo = (int a) { writeln("It's a variable! : ", a); };
     //5.foo();
     foo(5);
}

no warning.

but with uncommented `5.foo();` there should be a warning.

shadowing global functions with locals is not a big deal in a good written
code, but remembering that UFCS ignores locals and picks globals instead is
something that should better be told by the compiler.
