[swift-evolution] [Pitch] Including yes/no in stdlib as aliases for true/false

[Josh Parmenter]

I agree - please - just don’t. This is easy enough to create on your own if you wish, but I think it is easier for new developers to the language not to have to ask what differences there are between ‘true’ and ‘yes’ and ‘YES' … etc

-1 from me. We should not introduce two equivalent spellings for the same thing.

(Yes, there are sometimes multiple ways to accomplish something, but they are not nearly this close.)

I propose adding yes and no to the standard library as aliases for true and false Boolean values. When answering the questions posed by Boolean properties and methods, "yes" and "no" may provide better fits than "true" and "false".  "Should this view be hidden?" "Yes!" "Does this collection contain the number 2?" "No!". Objective-C solved this by adding macro equivalents, admittedly with some attendant fuzziness because boolean implementation details allowed non 0/1 truth values.

Swift on the other hand has very firm ideas about true and false. Adding yes and no literal aliases would enhance code readability with little cost. There's minimal historic support among languages for yes/no but Swift is an Apple-y kind of language and yes/no is an Apple-y kindness to developers.

I performed a gmane search and did not find a previous thread on this subject.
