Perl may work in this role but I have to admit I really dislike it's syntax, and as such I never learned Perl enough to love it. and while most other scripting languages can technicaly create pipelines, it is very awkward compared to shell.

I've been working on a design for a Python library to facilitate this sort of thing.
