features and backwards compatibility

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I would love if there was an official reference listing features and backcompat alternatives. So far, I've only found these:

feature	first released	module	mincompat
fc	5.16	Unicode::CaseFold	5.8
defer	5.40	Feature::Compat::Defer	5.14
class	5.38	Feature::Compat::Class	5.18
try	5.34	Feature::Compat::Try	5.14
builtin	5.36	builtin::compat	5.8
builtin	5.36	builtins::compat	5.8

Can you think of any others?

For subroutine signatures, I wrote Filter::signatures. I don't use (or recommend) it anymore since 5.20 has been released a long time ago, but it is backwards compatible down to 5.8 or 5.10. There are also signatures and Function::Parameters, which are still maintained.	[reply]

Not sure if I'm understanding you correctly, but have you seen: perldoc feature?	[reply]
