Hey Tyson,

I voted "No" on this one, sorry.

TL;DR: I'd rather have a mechanism to disable global function fallback, not
something that makes un-imported symbols immediately global.

The idea to disable PHP's implicit
"fallback-to-something-that-may-or-may-not-exist" is great, and it could
simplify some of the engine, as well as remove some caching mechanisms
(lookup) in some contexts, but I'm pretty happy with disabling all global
lookup functionality, rather than making them the default.

I don't have a problem with `use function sprintf;` to import things from
PHP, and actually use it to quickly grep whenever I do something extremely
dangerous (like `use function umask;`).
This gives me also a good overview of how much of the global symbols are
still in my system, and to be replaced with something like
`thecodingmachine/safe`.

I also deal with merge conflicts regularly: not a big issue either.

Greets,

Marco Pivetta
