-----------
deprecate the ':all' feature bundle
As discussed in perl/PPCs#60, `:all` is very unlikely to be useful.
Since it will enable all features a future Perl might support, it will
also enable some that might be incompatible with the code as written
(see `bitwise`, for example, which changes the meaning of the existing
bitwise operators).
With the addition of "negative" features in v5.32, `:all` became even
less useful, since it would re-enable features deemed undesirable in
modern Perl.
As this point in time, `:all` is effectively a footgun.
If the keyword `all` (from PPC0027) is added as a feature, there's an
extra risk of confusion between `use feature 'all'` and `use feature ':all'`.
This patch makes `:all` warn. We should consider removing that bundle
entirely in the future.
