What you want is implicit function template instantiation based on the
return type. D doesn't do that, it doesn't even allow overloading based
on the return type. However, you can infer the return type using auto:
auto inv(T)(T m)
{
return 1.0/m;
}

Hello!
I guess, i am unable to express myself.
In code :
T inv(T)(T m) {
return 1.0/m;
}
If we forget the rules of default literals that C derived languages have,
just for a second.
And enforce our own little rule.
- no implicit casts
With this in mind this code says; i gave you T, give me T in return,
perfectly clear i guess?
Now when you call the function with a floating point, real, double,
float..., you will get what you asked for.
Now what about other types? Say you call it with a non floating type, when
compiler tries to divide the first thing
it will encounter that one of two elements of the operation is a
non-float, since we enforced a rule, it gives warning or error.
Thanks!
