Couldn't one write ACME::Include based on source filters instead of the DB way you gave above?

Source filters are a bad idea in general, but note that this one does not attempt to parse perl code, so it can not be fooled by wierd-looking perl code like some source filters can be. I still don't say that soing such things would be a good idea, but it might be cleaner that the DB hack.

Here's my example, which just a quick draft, does not handle line numbers etc.

Filter/ is

package Filter::Include; use warnings; use strict; use Filter::Util::Call; sub import { @_==2 or die qq{usage: use Filter::Include "filename"}; open my $f, "<", $_[1] or die qq{cannot open include file "$_[ +1]": $!}; read $f, my $d, -s $f or die qq{cannot read file "$_[1]": $!}; filter_add(sub { $_ = $d; filter_del(); 1; }); } 1; __END__

first is:

#!perl -w use warnings; use strict; my(@a, @b); @a = ( 1, 2, do{ use Filter::Include "./second"; }, 7, 8); print "a(@a) b(@b)\n"; __END__

and second which has to be in the current dir when first is run:

3, 4); @b = (5, 6,

Then, perl first prints a(1 2 3 4) b(5 6 7 8)
