BTW, why is there a limit to the number of constants?The motivation was to limit the number of hist_fields that can be created for constants. These are also indirectly limited by the max number of subexpressions (3) and the max number of vars/keys that can be defined, so I don't feel strongly about keeping it.
Yeah. I see the limiting factor is the number of expressions and such. And as described in my other email, if you have two constants for a single operand, you can easily combine them into one. -- Steve
