Bug report

When filling array in foreach, type of final array is weird - it unions all keys together and also unions all values together so it looks like each key can have any value type, but that's not truth.

Code snippet that reproduces the problem

Expected output

Type should be something like array{a: 'asdfghi', bd: int<1, 1000>, be: int<1, 1000>, cd: int<1, 1000>, ce: int<1, 1000>} and it should be accepted by array{a: string, bd: int, be: int, cd: int, ce: int}
