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 I need it for an empty tuple
is one of the most likely scenarios.
I see. Then a good idea is to create a little function, to solve
this. It should contain a static if that tests for the empty
tuple and returns false in that case, and otherwise uses the
canFind.
