If we think strictly in terms of effort to implement (and ignore maintenance costs or what's required to reach the same quality levels etc) then it shouldn't be an unreasonable amount of effort to do a Swift implementation - and in fact we could look at both approaches and see which is preferable (as both approaches have been taken by Swift frameworks already).

Ahh common! :-) The http_parser is just the parser. nghttp2 is a full HTTP networking library, pretty much a C++ version of what this groups wants to come up with! Included in your LOC is stuff like a `memcached_dispatcher.h/.cc` and `ruby_module.h/.cc` …

Do you really want to use nghttp2? Unlike the name suggests this isn’t a plain-C thing, it is actually a C++ code base. Scanning the code it looks like that would bring in the C++ stdlib, Boost!, libevent and who knows what. This is fine for Node which is C++ in the first place, but I really don’t find it desirable to pull in such a big thing as part of this effort.


P.S.: As a sidenote, can’t someone (hm hm, who would come to mind?) sponsor the CryptoSwift guy to do a java.security like Security standard framework (which includes TLS)? That would be pretty cool :-)
