try this:
unless (/^[-\.\w]+$/) { print "you cheater!" }
this will check if from beginning to end of $_ it contains - . (not even sure
you need to \ the . ) or any word character (a-z A-Z and _ )
the ^ says to start at the beginning of the string... the $ says to read till
end of line...
i'm on a machine without perl here, so the string is untested...
