Ambiguous operators in first arg of method invocation RB-LI1002
Bug risk
Major
Autofix Params to the method are passed without parentheses. Presence of some operators,
like +, -, *, ** and &, make the method invocation look ambiguous.
Bad practice
# the code is interpreted as invoking method f with a positive number a,
# but it could also appear as addition to a reader
f +a
Recommended
# With parentheses, there's no ambiguity.
f(+a)
