Regarding the union type RFCs, from what I remember, one of my personal issues with it were the complex rules involving scalar type unions in weak typing mode. It's non-trivial to decide what a value should be casted to if it does not have the correct type. It's sort of clear what "1.5" passed to an int|float union becomes, but it's not intuitively obvious what should happen if you pass "foo" to a bool|int union, etc.
in case of "bool|int" cast it to bool in case of "int|bool" cast it to int first comes, first serve -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
