a and b are typenames, not variables. You can't use aliases either since they don't accept variables:
template mul(alias a, alias b)

The only thing that will work is a tuple:
template mul(V...){ const mul = V[0] * V[1]; }
And for a complex expression, that isn't very pleasing to the eye.


You were right about not needing 'auto'. I didn't think D allowed that though.
