granted the code referenced in:
Found in /System/Library/Perl/pods/perlfaq7.pod
How can I pass/return a {Function, FileHandle, Array,
Hash, Method, Regex}?
that comes with the default perl 5.6.0
recommends that one check the pass by reference in perlsub
and the typeglob section of perldoc perldata
where we notice:
" Temporary Values via local()
WARNING: In general, you should be using `my' instead of
`local', because it's faster and safer. Exceptions to
this include the global punctuation variables, filehandles
"
but provides the same 'splutter(\*STDOUT)' type of
passing a typeglob around...
all of which leads me back to the question of whether your
position here is advocating something on the order of
open(FH, $filename) or die "no open $filename:$!\n";
my $fh = fileno(FH);
goSubBeatState($fh, @mess_to_grovel);
or should we have gone through IO::Handle to begin with????
or is the problem here that passing file handles around is not
always a really smart thing to do to begin with????
I know that I have code where I pass around the FD for a socket....
so catch me up here homeboy - what is the orthodox trick?
