Subject: [ruby-core:43505] [ruby-trunk - Feature #6180] to_b for converting objects to a boolean value


Issue #6180 has been updated by AaronLasseigne (Aaron Lasseigne).


Typically this comes up when you have a method ending in a question mark to indicate a boolean return value.

def foo?
  !!@foo
end

def has_vowel?
  !!(value =~ /[aeiou]/)
end

When a boolean return value is required it has become common practice is to use "!!" to convert the object. It would be more consistent to provide a "to_b" method on Object.
