A very delayed thanks to both of you. It does seem like it would
be useful to have something like a hasSignature!(Fun, Ret,
Args...) defined in
The other way is better, but since you asked...

Hi,
What's the best way, when using a Callable as a template parameter, to
constrain it by signature?
For example, if you have a function that sorts an array like so:
T[] sortArray(alias less, T)(T[] arr) { ... }
Then you know that you'd want `less` to
