Alex, no worries -- not everyone is optimizing for the same things. For our
team, things like async stack traces have proven valuable to speed up
debugging.
The way we use streamline, we never have to explicitly compile. We just
call require('streamline').register(...) at the top of our main module, and
then the streamline runtime automatically re-compiles any streamline source
files if needed (and persistently caches the results) as they are
require()'d along the way. so while technically there is compilation going
on, it's a JIT process, completely transparent and painless in my
experience. In other words, the streamline language still feels like
javascript, the streamline dev experience still feels like javascript (no
explicit compile).
Generators certainly seem to be the future for javascript. Streamline can
target generators as one of its backends btw. However, as you point out,
generators are still pretty early. As part of that, if you look at the
performance tests (https://gist.github.com/bjouhier/5554200) that i
referenced in the blog post, you can see that the results with generators
lagged behind, at least as of when these tests were done.
