Subject: Is this possible in Ruby


Just an idea which may come in handy. Can this be done and how in Ruby.

def calc(what)
  some_eval(what)
end

a=10
b=12
calc('a+b') # expression as parameters
=> 12   # would return

a='aa'
b='bb'
calc('a+b')
=> 'aabb'

This is of course strictly hypothetical. I would like the expression to
be evaluated inside the method using variables which are local to the
calling part.
