Any ideas for more generic names?

I'm not sure I undestand what you mean. An identifier without quotes is evaluated immediately. Could you give a short example of what you think?

Yes, but the quotes work only when the identifier is by itself, not inside an expression. The idea is that 'X.+2' evaluates X immediately, because the user "requested" it by adding the trailing dot.
There should be a command to make certain variables in an expression evaluate, perhaps:
'X^2+Y' 'Y' ->EVALNOW would produce the expression 'X^2+Y.' which would cause Y to be evaluated immediately next time the expressions is executed or operated upon. If Y is 4, then:

'X^2+Y' 1 + --> 'X^2+Y+1'
'X^2+Y.' 1 + --> 'X^2+5'

In the second case, only the Y was evaluated automatically, X will not be evaluated unless EVAL is called on the expression.

What I meant is that the name ->APPROX doesn't really work for variables, should be something like the EVALNOW above.
