Actually I don't realy feel the need for this feature, I just happened to read this: http://lambda-the-ultimate.org/node/view/58#comment And I realized that I did not knew if this was possible to do in ruby, so I asked on the list :) # further delirium I think this could be an interesting feature, for debugging purposes and (maybe) to satisfy people that wants stricter checks (i.e. we could provide required variable declarations like perl strict, or checking attributes of the objects being assigned to variable. We could provide first-win behaviour where a progtram could raise an exception whenever a global variable (even instance and locals, anyway) got its value changed from the existing type to an incompatible one due to an error (please don't think type==class) and other little nifty things.
