I still think something is wrong...

If I do something like:

mkdir dir1 dir2
touch dir1/f{1,2}
[download]

and then run:

foreach (1,2,3,4) {
print "dir1\n" if glob("dir1/f*");
print "dir2\n" if glob("dir2/f*");
}
[download]

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*");
[download]

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.

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
