What a terrible post!

After all this time, you still can't write a syntactically correct anonymous internet slur.

• 'posting on perlmonks' - Perhaps you meant 'PerlMonks,' the proper noun?
• 'valid line of perl' - Perhaps you meant 'Perl' the language, not 'perl' the interpreter?
• 'code that uses grep golfing' - Perhaps you meant 'code, which uses grep, "golfing"', or maybe you simply eschew punctuation at unpredictable moments. Stack overload inside your cranium?
• 'hes stupid' - Perhaps you meant 'he's stupid.'?
• 'a non-programming piece of poo' - Perhaps you meant to say that the Monk in question has no redemptive value because 'he still can't write a valid line of perl' (an overstated assertion and a hyperbolic conclusion even if you were trying to be mean)? If so, perhaps you should consider your linguistic shortcomings in your native language that you so succinctly have placed on display here.
