Hm, so with new strict type scalar hints it is turned on via per file
(not global) basis, and whether something is strict or not is dependent
on the declare being in the file that makes calls to the functions, not
the file that defines the functions.

Doesn't that seem sort of weird?

If using a third party library that expects things to be on a strict
basis, the library can't enforce the strict behaviour, it requires the
user of the library to include a declare strict at the top of their file
that makes use of it.

What happens when two external libraries are being used, one which
assumes the user is operating in strict mode, while the other assumes
not?
