water again. I am leaning towards returning to Emacs... does anyone know here if there's a mode that does syntax checking (eg 'strict' and 'warnings' in real time)? I know about cperl for syntax colorization, but, again relfecting back on optiperl, it squawks in real time when I type  $fooo when I should have typed <code $foo</code>, or if I type  gep rather than  grep. Seeing the error at that instant and fixing it right then is a big time saver, vs. seeing the error when syntax checking or running the script. Does anyone know if emacs can do something like this?

Thanks!
