Hi again,
In an attempt to be constructive, I have implemented an alternative
approach to weak scalar type selection here:
https://github.com/krakjoe/php-src/compare/multi-types...TazeTSchnitzel:multi-types-roulette
Where there is no exact scalar type match, this patch uses an algorithm
originally suggested by Nikita, wherein we use rand() to pick which type
to cast to.
This is much simpler than having a type precedence matrix, and thus is
easier to remember and reason about. The choice of selection function
means that no particular use-case is privileged. Given PHP's scalar
types are roughly equivalent (after all, PHP juggles them freely), this
apparently unorthodox selection process should nonetheless produce
sensible results in most cases.
Please tell me your thoughts!
