On one hand I do like the idea that it's a shell since it means in it's nicely integrated with itself (can't think of a better phrase), but on the other hand it's also what's making me a bit reluctant to seriously consider it because I'm too used to fish.

It would be ideal to me if it were a tool that could be piped into.

However, that's not to say I won't at least give it a try these days, since I'm really curious about it.
