we must have different versions of something.
when I run that code id get the following error

erickn@hestia:/home/erickn/wo> perl x "looks_like_number" is not exported by the Scalar::Util module Can't continue after import errors at x line 5 BEGIN failed--compilation aborted at x line 5.

line 5 is the use line

I'm using perl 5.8.0
It looks like Scalar::Util uses List::Util and that version in my system is 1.07_00
any ideas?
