I agree. I love Ruby. Not just the language, but the values of the community. Don't give up. Try SciRuby. I also recently discovered pycall, for those times when something…

Sure! It's quite simple: works like a charm. Completely transparent. You `import` with Python-like syntax, and you get a Ruby object that transparently forwards any message (i.e. method calls) to the corresponding Python object on the underlying Python interpreter. This means that Ruby does not need to know _anything_ about the Python object: whatever you call on the Ruby object is just forwarded to the Python one, and whatever result is passed back to Ruby. About the overhead, I sincerely do not know; I expected to have some so my code does part of the image pre-processing directly in Python (`narray`) in order to pass a smaller object to Ruby, but besides that I could perceive none -- grain of salt advised, as that was possibly hidden from me because my computation in Ruby was orders of magnitude more complex/time consuming than what w

Personally, I am a fan of his work and elegant approach, I owe him for enabling me to keep working in Ruby while everybody publishes code in Python :)
