  One of the few things I like in Groovy that Ruby doesn't support is 
the '?.' operator. For instance:

obj?.somePropertyName?.anotherGreatPropertyName?.anotherOne

This is the same as:

(obj null ? null : (obj.somePropertyName null ? null : 
(obt.somePropertyName.anotherGreatPropertyName null ? null : 
obt.somePropertyName.anotherGreatPropertyName.anotherOne)))

Unfortunately, this name cannot be used by Ruby since it accepts '?' as 
part of a method name. I've seen some framework that declares a '_?' 
method for doing this like 'obj._?.some_method._?.another_method'.

I'm not sure what syntax would fit better for Ruby. I don't even know if 
this is something the Ruby community is interested in as well, so I'd 
like to hear your opinions on this feature.

Regards, Rodrigo.
