I was using some templates to declare different parameters sets.

template unitA() {...}
template unitB() {...}
template unitC() {...}

I have a generic function that is parameterized by these units.
void foo(alias unit) {...}

Now unitA gets a specialization.

void foo(alias unit:unitA!()) {}

But here I'm a little stuck because this won't work in my case due to a
bug (there are more parameters).

Does anybody know of a way to test an alias for identity.

void foo(alias unit) if(unit == unitA!()) {} // won't work of course

martin

This will do the job:

void foo(alias unit)() if(unit.mangleof == unitA!().mangleof) {}

Thanks, better than the .stringof I resorted to.
