Also why not be able to write this (yes I know we can use Filter!()
but this is just an example):
template GetIntegrals(Types...)
{
foreach (T; Types)
{
static if (isIntegral!T)
GetIntegrals ~= T; // GetIntegrals becomes a typetuple
}
}
This beats the whole recursive template madness which we always have
to write (again there's the D language, and the "template" language,
just like in C++)
Maybe it would even speed things up not having to recursively
instantiate the template many times.
