Your second version seems more perlish to me, although I'd
probably fiddle with some of the names and it's not clear
why you have the array-ref brackets. I'd suggest:
my($read, $write) = kpipe(...); #korn (cob) pipe!
#... is a string that is parsed a la ksh syntax, or a pre-decomposed list:
# 'mutt', '-a', ksub('<', 'gzip', '-c', $some_file), '-s', 'mmmm data', '--',
'j...@example.net'
You might allow kpipe to accept an existing pair of handles,
although it seems unlikely that would be needed/could be worked
if not officially supported.
