I'm trying to pass a function pointer while keeping the default
parameter values intact. Given the following:
import std.traits;
import std.stdio;
int foo(int a, int b = 1)
{
return a;
}
alias FOOP = int function(int, int = 1);
struct ST(POOF)
{
FOOP fctn;
this(POOF fctn)
{
this.

Intended, the mixin template works on the basis of names. This
means that you can override methods from the mixin by writing a

std.conv.to really should be able to do this, but I guess not
many people have needed to do this. You can write an
"extension" to `to` which does it for you:
import std.traits;
auto to(To, From)(From f)
if (is(From == enum) && is(To == e
Note that this is a very simple example. You need to check in the
function that a valid StyleColor will actually be produced.
Otherwise, it'll happily produce a StyleColor that's invalid.
