Arithmetic operator following parentheses-less method gives ArgumentError
Bug #9611: Arithmetic operator following parentheses-less method gives ArgumentError
Description
It would be better to explain this with an example:
> 'a'.length -1 ArgumentError: wrong number of arguments (1 for 0) from (pry):1:in `length' Other ways of writing this expression work as expected:
> 'a'.length() -1 => 0 > 'a'.length-1 => 0 > 'a'.length- 1 => 0 > 'a'.length - 1 => 0

Even though this also happens with +, * and /, I guess it is on purpose to pass negative numbers, not a bug. My mistake.

Yes, this is well-known (but often misunderstood) ruby's spec.
