@myabc one tip if you want your 1.9 code to work with 1.8 is to use the backports gem. Granted you can't use 1.9 syntax like stabby procs or the new symbol key syntax in hashes, but otherwise you can write the code as normal. The backports gem basically updates the 1.8 core/stdlib to work like 1.9's.

Granted, this is more applicable to libraries, but still not bad for apps.. since you can use things like ree which may still perform better than 1.9 in certain situations.
