Can somebody show me examples of prototypes used in Perl and why they are bad.
Please show me a bad example of protoypes and then show me the correct way of writing. Please use simple examples so that I can copy and paste your examples on my computer and run them my self.
I have read Tom's excellent note on prototypes but it's a little too advanced for me, I need to take baby steps for now, and then I'll go back to Tom's article on prototypes. TIA
