Our application accepts String containing user-defined arithmetic expression
and needs to validate and evaluate it. My QA has opened a bug report saying my
solution does not accept valid arithmetic expressions that our customers may

bug. It is not far fetched to say it should be critical.
PS, Although the Language Elements page mentions only the unary minus operator,
*it does not explicitly specifies that unary plus is invalid*. Something that
devs may easily overlook when evaluating whether or not to use this library (as
I have done)
