@lnxw48 I've never looked at the pump API, so I don't know how limited (or not) it is; but I think Evan wanted a clean start instead of starting with an existing API and then cobbling things onto that. It makes sense, of course, but one has to imagine a lot of use cases to design a good API that is powerful enough. And it's a fact of life that programmers are often surprised by *how* people actually use (or attempt to use) their product... so designing an API isn't all that easy.
