Common sense dictates that you shouldn't declare subroutines with the same name as one of Perl's built-in functions. See `perldoc perlfunc` for a list of built-ins.

  sub open {}  #not ok
  sub exit {}  #not ok
  sub print {} #not ok
  #You get the idea...

Exceptions are made for BEGIN, END, INIT and CHECK blocks, as well as AUTOLOAD, DESTROY, and import subroutines.


It is reasonable to declare an object method with the same name as a Perl built-in function, since they are easily distinguished from each other. However, at this time, Perl::Critic cannot tell whether a subroutine is static or an object method.
