If we removed just subroutine prototypes rom the language the proof would not hold any more. So the question is is there a more general proof that does not rely on prototypes?


BEGIN { eval "sub foo {}" if rand() < 0.5; } foo 'x';
>perl -c syntax OK >perl -c String found where operator expected at line 5, near "foo 'x'" (Do you need to predeclare foo?) syntax error at line 5, near "foo 'x'" had compilation errors.

Execution is required to decide whether foo is a subroutine call or a bareword.
