"Basically, prototypes are not for catching errors at compile time. Rather, they're for changing the precedence of the subroutine calls." 
% perl -le 'sub f ($) { print @_ } f(1, 2)'
Too many arguments for main::f at -e line 1, at end of line
Execution of -e aborted due to compilation errors.
% perl -le 'sub f ($) { print @_ } f()'    
Not enough arguments for main::f at -e line 1, at end of line
Execution of -e aborted due to compilation errors.

Prototypes have been catching errors of this sort since 5.002.
