--- Comment #1 from Daniel <wyrlon at gmx.net> ---
I was just hit by this bug as well.

It's possible to workaround with string parsing, but not pretty.

static if(is(FunctionTypeOf!T P == __parameters))
{
  enum decl = P.stringof[1..$-1]; // hack, strip parenthesis
  // parse decl
}

For a proper fix, __traits(identifier, ...) needs to work for function
literals.
