It's easy to mis-spell `rx.var(cached=True)` instead of `rx.var(cache=True)`,
and in 0.6.3, this doesn't actual raise an error... the bad value is silently
discarded and the var is NOT marked as being cached.
All generic types present in a Union must be parametrized on 3.11.0 if any
other generic types in the union are parametrized.
This appears to be a bug in 3.11.0, as the behavior is not observed in 3.11.1
or 3.10; fixing here as this is technically more correct anyway and avoids a
crash.
* [ENG-3954] Treat ArrayVar.foreach index as int
* foreach: convert return value to a Var
When the value returned from the foreach is not hashable (mutable type), then
it will raise an exception if it is not first converted to a LiteralVar.
