This looks like a whole lot of work for a 0.0.1 release so I must ask... why might I choose Ice over Flask?
Even more: why WSGI ?
We need a django of the async world. We need something in Python to compete with nodejs, or even meteor, with async/await as primary tool. And maybe a aWSGI support.
But WSGI ? We have everything we need. They are proven tools. They work. Have great ecosystems and documentations. They do the job perfectly for non real time oriented web site. We don't need another one.
Seen Sanic[1] yet? I've become a fan... works well with asyncpg[2] too.
