Haven't you seen my answer about constraint ?
If you put a constraint on your function template then invalid
instantiations are rejected. I mean... this language feature is
not just ornamental...
What do you think constraints are used for otherwise ^^
Yes, I've seen it, thanks.
Requiring the user to write the constraint might indeed enforce a
better style, but I want to be able to test it even if the user
forgets the constraint. Otherwise she'll get cryptic error
messages from some other code assuming that CallsFoo!NoFoo is a
valid type.
