Re^2: writing a pragma

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.

thanks for the answer. helped a lot. is there a way to write a module to work like strict. so that does something at compile time?	[reply]

In Perl it is easy to do things at compile time. You have `BEGIN` for that. A different mater is changing how the program is compiled. `perl` provides some hooks for doing it, but AFAIK, it must be done at the C level and requires a pretty good knowledge of the internals.

That really depends on exactly what you want to do at compile time, doesn't it? Some things are easier than others. `use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name`	[reply]
