> Perl nowadays have TypeScript-style type checking for function parameters. I can't believe that. TS code, compile time error "TS2345: Argument of type 'null' is not assignable to parameter of type 'number'." function foo(x: number): void {}; foo(null); Perl code: use Kavorka qw(fun); use Types::Standard qw(Num); fun foo(Num $x) {} foo(undef); This code passes CHECK (perl -c), but should not if you are correct. I invite you to prove the claim. Rewrite this with any module you like.
