in thread Stopping bad input (harder than sanitizing)

Here is something new: I also wanna catch '[' (for [(1)). But when my expression is $_1 =~ /^[\w\s:-\[]+/ it spits out an error and says "stack moved" (is that PERL humor?). How do I add '[' to the character class? When I press <RET> with no data, the program still locks up.

The hyphen in the middle is significant. Move it to the end if you want it to be a literal. 🦛	[reply]

Please put perl code inside code tags, it's not possible to tell just what you entered.	[reply]
