If all you want to do is play with `%INC`, instead of actually inspecting the symbol table properly, then you might as well use the standard core module, `Module::Loaded`.	[reply] [d/l] [select]

What version of Perl did Module::Loaded become core in? I'm using 5.8.8 and it is not available there. `$ perl -MModule::Loaded Can't locate Module/Loaded.pm in @INC (@INC contains: /usr/lib64/perl5 +/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5 +.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_ +64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5 +/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/li +b/perl5/5.8.8 .).

`$ corelist Module::Loaded Module::Loaded was first released with perl v5.9.4` [download] I'm on 5.12.2. See also New modules	[reply] [d/l]

Kind of. Remember that a file can define more than one package, e.g. `$ echo 'package A; package B; 1' > A.pm; perl -MA -le 'print for keys +%INC' A.pm` [download] If you want to know if a package is defined, rather than whether a correspondingly-named file has been loaded, the OP's approach is correct.
