Fix operator precedence for unary + and - #150

Closed rbergen closed 2 years ago

rbergen commented 2 years ago

This fixes #132. It does this by including the arity of an operator in the precedence dictionary and lookup.

Interestingly enough, the existing comment 

# key is tuple (token, nargs)

above the PRECEDENCE dictionary seems to indicate that the operator arity was included in the dictionary key at some point in the past?
