Like I already updated, you can drop the parentheses (and &-sigils if any) to enforce compile time checking.

FWIW: If you want this to happen with parentheses too, it's theoretically possible to write a module/pragma parsing the OP tree at the CHECK or UNITCHECK phase to abort compilation in case of absent subs in the namespaces. (See perlmod for phases)

I think I know how to implement this particular feature, but that's none of my itches to scratch. 🤷🏻‍♂️

Maybe worth checking CPAN before reinventing the wheel 🛞 (I haven't)
