Nice work brother stephen. I do have a small comment on your example for "Choose." You are effectively using the hash as a replacement for a switch statement (since Perl doesn't have a builtin switch). For this type of use I would recommend taking a look at Damian Conway's Switch module. It allows you to use a real switch statement with all the power of perl for the case comparisons (e.g. it's not limited to integer case values like the C switch statement). Damian stated at YAPC America::North 2001 that his switch module was going to be added to the Perl core so I would presume it's a fairly "safe" module to use. Regards,
