Subject: [ruby-core:43511] [ruby-trunk - Feature #6180] to_b for converting objects to a boolean value


Issue #6180 has been updated by trans (Thomas Sawyer).


Also, what you are asking for should probably be called #to_bool. 

Where as #to_b can have a broader, and generally more useful definition, e.g.

  "true".to_b  #=> true
  "yes".to_b   #=> true
  "on".to_b    #=> true

  1.to_b  #=> true
  0.to_b  #=> false

and other such useful humanistic forms of expressing truth.

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.
