solution is to use std.traits, but can someone explain this to me?

The 'function' keyword is an ugly wart in the language. In
void function()
'function' means 'function pointer'. But in
is (X == function)
'function' means 'function'.
Which is actually pretty much useless. You always want 'function
pointer'. This is the only case where "function type" still exists in
the language.
