Is there room for a lightweight scriptable language that takes the place of, say, bash/zsh/korn/fish shell scripts?
Please don't say perl/python or sed/awk.
I use POSIX /bin/sh exclusively. It's reasonably lightweight but because of this you loose a lot of the "bash-ism"s. There's ways to work around it though, and the pure-sh-bible[1] is great.
