This would have been great 10-20 years ago, or even at the coining of Unix pipes. By today's standards, however, the syntax feels clunky and dated. I'd like to see contemporary shells like nushell and elvish copy these ideas, with attribution of course, in a more modern way. That is the best way I can see to honor this stagnant project: https://github.com/dspinellis/dgsh
