Sure. You can check the source code of strict at (Meta-)CPAN: https://metacpan.org/source/RJBS/perl-5.18.2/lib/strict.pm. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply]

Well, strict is not a good example as it is just a thin wrapper to enable/disable functionality that is actually implemented on the C side of the perl interpreter. How to write pragmas is documented in perlpragma. The entry for `%^H` in perlvar contains also some bits of information.	[reply] [d/l]
