Re: Finding when a feature or keyword was introduced

Regarding features, the documentation of feature lists the minimal Perl version for each feature.

Regarding keywords, the ones not covered by features (i.e. everything but fc and say) are as old as I remember, so probably pre-5.6. There's no need to bother with so ancient versions.

There are some things that were introduced over the years that weren't mentioned in the deltas or they were but the required version isn't mentioned in their documentation. That's why I created Syntax::Construct.

Update: Reformulated. fc and say are examples of keywords covered by features.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

`say` is enabled with `use v5.10` which implies it was introduced in that version. Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond	[reply] [d/l] [select]

It doesn't list the versions for try (5.34) and defer (5.38) features. Both are still experimental as of 5.38.	[reply]
