Hi bcrowell2,

If you peek into the source for File::Glob, you'll see that csh_glob is a separate, undocumented method, which is not directly related to the method GLOB_CSH (which is documented, and just sets a bunch of flags).

Furthermore, there's a comment: 

# NOTE: The glob() export is only here for compatibility with 5.6.0.
# csh_glob() should not be used directly, unless you know what you're 
+doing

And finally, you'll see that there's a hash %iter (documented as "## borrowed heavily from gsar's File::DosGlob"), which is used the very first time to hold the results from dos_glob, and after that, returns the next value in the already-created list.

s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/
