Let Kernel#lambda always return a lambda

Feature #15973: Let Kernel#lambda always return a lambda

Added by alanwu (Alan Wu) over 7 years ago. Updated almost 5 years ago.

Description

When Kernel#lambda receives a Proc that is not a lambda,
it returns it without modification. l propose to change Kernel#lambda
so it always returns a lambda.

Calling a method called lambda and having it do nothing in effect is
not very intuitive.

Judging from marcandre's investigation here: https://bugs.ruby-lang.org/issues/15620#note-1,
changing the behavior should not cause much breakage, if any.

This also happens to fix [Bug #15620]
