I still think something is wrong...

If I do something like:
mkdir dir1 dir2 touch dir1/f{1,2}
and then run:
foreach (1,2,3,4) { print "dir1\n" if glob("dir1/f*"); print "dir2\n" if glob("dir2/f*"); }
I get 'dir1' printed 3 times (NOT 4). But if I unwind the loop:
print "dir1\n" if glob("dir1/f*"); print "dir2\n" if glob("dir2/f*"); print "dir1\n" if glob("dir1/f*"); print "dir2\n" if glob("dir2/f*"); print "dir1\n" if glob("dir1/f*"); print "dir2\n" if glob("dir2/f*"); print "dir1\n" if glob("dir1/f*"); print "dir2\n" if glob("dir2/f*");
Then I get 'dir1' printed 4 times!!!

In other words, I can understand why 'glob' is stateful when it is the loop iterator. But it makes no sense (to me) (and seems wrong) for it to be stateful when it is not the iterator. Because then unwinding a loop give a different answer.

    [haukex]: But I was just using it as an author test anyway
    [Corion]: haukex: Aaah - I thought you were still running these tests on every machine, but you only run these as author or Devel::Cover tests
    [Corion]: haukex: Yeah, I think back then I used Test::Inline, which used a pod parser that was going through some changes and I didn't want to cater for all the various versions and thus stopped testing the Pod completely
    [choroba]: I usually do this with presentations
    [Corion]: But now I think statically (re)generating the Pod tests is a saner approach, and likely I'll regenerate the tests either in Makefile.PL or from xt/ but have them live below t/
    [choroba]: I keep the snippets in files of their own, and use a Makefile to syntax highlight them and insert them into slides, while also running them and inserting the output if required
    [Corion]: choroba: Ooooh - I didn't think of that! I write my presentations as POD and if it "roughly" looks like Perl code, I should also syntax-check that...
    [haukex]: Yes sorry I don't run them all the time, my POD tests are only run as author tests (and are excluded when I'm using Devel::Cover)
    [Corion]: choroba: Hmm - no, I keep the snippets inline, but as my framework also has support for capturing output etc., maybe I should do the same...
    [Corion]: haukex: Yes, that approach is sane, and it heals the fragility of Pod parsers in a nice way while still syntax-checking stuff
