OpMinus

open class OpMinus : Operator

The minus operator supports:

subtraction of numbers
subtraction of an int from a string of one character (effectively decreasing that character), so 'd'-3='a'

It can be used as a unary operator for numbers. The standard promotions are performed when the operand types vary (double-int=double). For other options it defers to the registered overloader.
