Hello!
Is there any websocket client implementation in D?
There's some WebSocket stuff here:
https://github.com/adamdruppe/arsd/blob/master/cgi.d
It's for server side, but probably contains stuff you need for
client too.
std.algorithm.reverse uses ranges, and shamefully DMD is really
bad at optimizing away range-induced costs.

Why is _accessing_ an assoc treated as indexing it?
Are you sure you understand "indexing" as we do? It's not like
indexing of databases, it's just "accessing by index" i.e. using
