Diggory:
Is the behaviour of the empty [] when applied to tuples
documented anywhere?
I don't remember.
The problem is that this doesn't work if the tuple is empty:
Error: template std.algorithm.canFind does not match any
function template declaration.
And unfortunately in the situation

Diggory:
It's not a TypeTuple, it's a tuple of strings.
Then one simple way to do it is to convert it into an array of
strings, and then use canFind:
[mytuple[]].canFind(needle)

OK, that makes sense but I'm not

The documentation seems too say that [mytuple] will make an

Nope. You have to extract the inherent typetuple first. And
this is what the [] syntax does (tested):
import std.stdio, std.typecons, std.algorithm;
void
