Ambiguous unary operator use with number constant
Reports an unary operator followed by a dot qualifier such as -1.inc().
Code like -1.inc() can be misleading because - has a lower precedence than .inc(). As a result, -1.inc() evaluates to -2 and not 0 as it might be expected.
Wrap unary operator and value with () quick-fix can be used to amend the code automatically.
