On the one hand, this seems fairly straightforward, and although casts wouldn't
normally appear on the left side of an expression, the intent is pretty clear.
On the other hand, this is exactly the kind of thing where strict_types=1 makes
things worse - you'll actually get *better* error output if you use
strict_types=0 and pass the string to a function marked as requiring int. By
forcing a cast, you're actually silencing the error, and turning all
unrecognised values to 0.
If the desire is for stricter type handling, we probably need stricter casts,
perhaps using different syntax like (int!) rather than just more places to put
the existing ones.
