And I forgot to add that large vocabulary sets can be off-putting (think FORTH which you either HATE or LOVE with little in between). For one, think documentation, and how much easier it would be to edit the existing list of functions and see a list of operators documented in one funcction location. It could be easier to jump to $(math ) in help and see relevant details listed together rather than in separate function definitions $(+ ), $(/ ), $(^ ), $(* ), etc. Of course these could be all in their own "grouping" in the manual, but again, sometimes using existing structures is better when possible, particularly as we tend to know that people kind of love to code new things and not spend as much effort on the documentation. In this case, I do concede, however, that a manual section called "Math", or whatever, could be a good thing if this ever comes to fruition. Oh, and yes, I think simple integer math in make is very intriguing as I routinely use make for implementing recipes that do all sorts of things that presently require shell code to keep thing readable.
