Good meeting this evening...
Someone asked me a question about what happens in Ruby when you have a
typo in your variable name and try to assign an undefined variable to
another like so:
astring = "this is a string"
b = asting
When you try to run ruby on this, ruby reports:
undefined.rb:2: undefined local variable or method `asting' for
So the fact that there has never been an assignment to the variable
'asting' is caught.
I've seen this many times, I'm not sure why I didn't remember that ;-)A
