Thanks for the formatting tips. Copy and pasting kind of messed up
the formatting, not that it was good to start with. I am still
developing a coding style.

Thank you for the reply. Potential, but there still seems to be
alot of repetitive code.

Not the whole truth though.
foreach over tuples gets unrolled at compile time so you can do stuff like:
// +=, -=, ...
Vector opOpAssign(string op, U)(U s)
{
foreach (i, _; tuple)

calling mixin a compile time has the following error...
Error 1 Error: variable func cannot be read at compile time

That's because funcs is mutable.
Try to make it immutable or enum.
