What fails if I want to define this:
Algorisme!(T,V) opBinary(string op)(Algorisme!(T,U) alg) {
Algorisme!(T,V) opBinary(string op, T)(Algorisme!(T,U) alg) {
You need to name what T is and that is *sometype*. Anyway I suggest
getting a decent book (TDPL).
if (op=="*") {
static if is conceptually and technically better here.
Thanks, Dmitry, for your suggestions, but it does not work too:
$ gdmd-4.6 algorisme
algorisme.d:54: Error: 'alg' is not of arithmetic type, it is a
algorisme.Algorisme!(int,int).Algorisme
algorisme.d:54: Error: 'alg2' is not of arithmetic type, it is a
algorisme.Algorisme!(int,int).Algorisme
I update de gist: https://gist.github.com/2429005
By the other hand, is there any way to put the definition of operator *
in the class (not out like I have now)?
it should be inside the class. Why would you put it outside and hope it
work? What 'this' can refer to in free function?
Please read spec at the very least.

Thanks,
