in reply to Perl + binary
There are no dumb questions, only dummies, that do not ask.
Is there a quick & easy way to check if a module is pure-Perl, or is Perl+binary for both CPAN and core modules?
No. Well kinda. Sure-fire-way is to look at he source.
$ perl -MCGI -MDBI -le " print for grep /CGI|DBI/, keys %:: "
so DBI.dll/DBI.xs/DBI.c means DBI is binary, lack of .c/.xs/.dll/.so means CGI is pure-perl
