There is an objection to using "cat" as the concat operator: it is not
backward compatible, because cat is not a reserved word in the current EL.
We now have several options.
1. Use "cat" as planned.
2. Use "el$cat" to reduce compatibility risk.
3. Use "+=" or "!"
4. Remove concatenation.
I'm OK with 1, 2, or 3, leaning towards "+=". Other opinions?
