in thread Array of operators ...

I used this exact approach when I was duplicating the PHP "date" function in Perl. Given, as you go to longer mathematical expressions, it'll probably be simpler to just pattern match for non-allowed characters (anything that isn't a number or limited set of operators) and then eval if everything looks ok.
