I actually love forcing people into a fairly consistent coding style, but everything else about the language irks me compared to my previous extensive use of Perl (on a large enterprise software product).

One particularly big thing, that it doesn't have much of a distinct compilation phase. You'll write some script you want to run to do some one-off task that will take the next hour, only to find it crashed after 20 minutes when it hits some boneheaded syntax error you made.
