Issue #15973 has been updated by akr (Akira Tanaka).
I'm against it.
Changing lambda <-> proc can violate the intent of programmers who write a block.
It seems good to raise an exception at lambda(&b) where b is (non-lambda) proc.

Feature #15973: Make it so Kernel#lambda always return a lambda

----------------------------------------
When Kernel#lambda receives a Proc that is not a lambda,
it returns it without modification. l propose changing `Kernel#lambda`
so it always returns a lambda.
Calling a method called lambda and having it effective do nothing was
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]
