In REXX, for instance, one can do a:
interpret y' = 4'
Since y contains a, then the above statement amongs to:
a = 4
There are many situations where this is useful. For instance, you might be
getting an input which is a string representing the name of a variable and
you wish to evaluate the expression (like a calculator application, for
instance).
