Weird template instantiation problem

[Arafel via Digitalmars-d-learn]

Well, I had kind of found a workaround (changing the return type to 
return the element and not the index) which I didn't like too much (what 
if there are duplicates?).

Now that I've found a "proper" workaround.... well, I'm still interested 
in knowing the reason, if possible, or if it's a bug.
