Hi gurus and nubys,

If you ever wanted to subclass hash but it was too hard..

If you ever wanted to write Hash::Regexp,  Hash::Approx and
Hash::Cannabinol in ruby, but felt that you have to implement too much
methods..

in general if you ever used YourClass#[]=(key,val)..

go vote for this rcr :)

Ok, stop cheerleading, the rcr is here:

A better name than Hashable (inexact) and Map (misses the -able
prefix) would be much appreciated.
