It makes the language more inconsistent, therefore more difficult to reason about. On the other hand, using a complex variable as reference in that context should be very rare outside obfuscation code contests. Therefore, I suggest to deprecate (and later remove) the ability to use of a complex variable as reference in that context. That would solve the inconsistency issue. —Claude
