        Odin:    dev-2024-12:6e1d02886
        OS:      Manjaro Linux, Linux 6.1.112-1-MANJARO
        CPU:     12th Gen Intel(R) Core(TM) i7-1260P

Behavior

typeids cannot be used in struct constants or arrays:

ThreeTypes :: struct {
	a: typeid,
	b: typeid,
	c: typeid,
}
TYPE_1: typeid : int
TYPE_2: typeid : string
THREE_TYPES :: ThreeTypes{TYPE_1, TYPE_2, TYPE_1}

This should work, since TYPE_1 and TYPE_2 are constants, but it does not, instead this error is emitted:
ThreeTypes{TYPE_1, TYPE_2, TYPE_1}' is not a compile-time known constant
