Right on. That's the great part -- both a simple way to program and re usability of libraries.

So far, I see library ecosystem fragmentation as the biggest issue of all and nobody seems to want to talk to it.

Academically all the yields and co-routines look so cool, in practice when you need 5 libraries to help with some task, and now you have to re-write them -- not so cool.
