Hello dear Perl Monks,
On a cross-post of the same question by the OP on the DevShed forum, I answered with a suggestion almost identical to Toolic's nested foreach loops.
However, this use of the glob function puzzles me. After some tests and reading in detail the glob description, I found this passage: "If non-empty braces are the only wildcard characters used in the glob, no filenames are matched, but potentially many strings are returned. For example, this produces nine strings, one for each pairing of fruits and colors".
So, now I understand why glob is being used in this context, but can anyone tell me why glob is doing this sort of things, which seems to have little to do with the normal usage of glob (by "normal", I just mean the usage that I have been knowing for years, i.e. returning filename extensions or a list of filename matching a shell file pattern)?
