Hmm, an interesting declination. Right now, I can't recall any Latin word ending
with -u, so I'll have to trust you on this.

There are two problems here:

 - MacPerl::GetFileInfo indeed contains a bug in the current release of MacPerl
   causing calls to randomly flake out. A workaround is to include a statement 
   "$! = 0;" before each call to MacPerl::GetFileInfo.
 - Your expectation that MacPerl::GetFileInfo returns "Fldr" when called on a 
   folder would be consistent with MPW, but this "Fldr" business is purely an
   MPW artifact with no counterpart in file system reality.
