For portability, you should get out of the habit of thinking of "*.*" as meaning "all entries in a directory." Just use "*" instead.

On Un*x varieties including Linux and MacOS X, the period is just another character which might be in a filename. On those platforms, "*.*" finds only those entries that just happen to include at least one period.

Windows thankfully expects "*" to mean "*.*", so using a single star parameter to glob() is portable on Windows and Un*x varieties both. 

my @subdirectories =
   grep { not /^\.\.?$/ }
   grep { -d }
   glob("*");

my @files =
   grep { -f }
   glob("*");

There is also a -T check which sniffs the head of a file for anything that doesn't smell like text, but I tend not to trust that kind of contents-check. It's not sufficiently clear if it would say true or false for a few UTF-8 or Latin high-bit characters, which I would still call a "text" file.
