maybe easier to get a majority from voters if defining union types only in
strict mode for 7.1?
No go, I'm afraid.
Strict types are opt-in at the point of calling the function, but union
types are a feature of the declaration. If I write "function foo(int |
string $a) {}", it is not up to me whether it's executed in strict mode
or not.
We'd have to throw an error of "function %s cannot be called without
strict types enabled", and that goes against the entire premise of
strict types as implemented.
