Perl is TIMTOWTDI but not every style is good style. It allows you to write down source which isn't executed the way you think.
Padre is not only "some open source project I'm involved", but a tool I'm using for every day's work. Yesterdays "svn update" brought a new bug, files as ticket #1286. Hunting down a newline issue isn't that easy, because many things from Wx events, encoding, line ending up to keypress-events or intelligent code suggestion may have the bug.
