I have a NumericUtil class that provides some standard PHP functions with a bit of a type-safety layer around them. Example : https://phpstan.org/r/9af1bd13-d40f-40f4-a611-18fd64980e99

Since migrating PHPStan from 1.4.10 to 1.5.3, I'm getting the inspection :

Parameter #3 $mode of function round expects 1|2|3|4, int given.

I've tried adding a PHPDoc @param for $mode, but couldn't a dynamic value that would work (expect hardcoding 1|2|3|4, which is a shame...). I tried listing the 4 constants PHP_ROUND_* separated by |, using the wildcard, with or without leading \, adding use const PHP_ROUND_...;, and it always just triggers another error...

Any idea ?
