No problem :o)

When posting here, I tend to forget that I usually either write throwaway
scripts (one time processing of a problem), or scripts that get run
occasionally on faily large servers. So far, considering processing time and
memory simply stepped into the background over finding a solution quickly -
if a script takes 2 minutes longer to run but took 5 minute fewer to write
while solving something immediate, that's a net win in most situations I use
ruby in.

You're completely right, though, it's far from best practices.

Felix
