@Scott Rudiger After thinking more about it.
I would not like to conflict with semantics of optional chaining and
null coalescing operator.
So in order to not confuse people, maybe introduce two types of optional
spread operators
1. `?...` - Do not spread if nullish. Note nullish. Else try to spread.
Signature Array: [?...(nullish | Iterable)];
Signature Object: {?...(nullish | object)};
2. `!...` - Do not spread if false. Note FALSE not falsy. Else try to
spread.
I read
!...foo
as
!(...foo)
that is, logical not. I'd tip it already works that way. In which case
no go, break compat.
Herby
Signature Array: [!...(false | Iterable)];
Signature Object: {!...(false | object)};
I think this can be an option to avoid consfusion
Or add a new one. :-(
