Subject: [ruby-talk:10289] Ideas for Ruby (A Python/Perl phrasebook)

FYI: This is an interesting link mentioned on comp.lang.python recently.

# A Python/Perl phrasebook
# 
# By Jak Kirman (jak@cs.brown.edu) 
# 
# This phrasebook contains a collection of idioms, various ways of
# accomplishing common tasks, tricks and useful things to know, in
# Perl and Python side-by-side. I hope this will be useful for people
# switching from Perl to Python, and for people deciding which to
# choose. The first part of the phrasebook is based on Tom
# Christiansen's Perl Data Structures Cookbook. 
# 
# I have only been working on this for a short time, so many of the
# translations could probably be improved, and the format could be
# greatly cleaned up. 
# 
# I will get the data-structures cookbook translated first and then go
# back to clean up the code. Please send me any comments or
# suggestions. 
# 
# Also, since I have been using Python for far less time than Perl,
# there are certainly idioms I don't know or that I will misuse.
