This RFC will provide details around the intention for adding support
for Unix Domain Sockets to the Pony runtime library and the `net`
package.

The intent would be to add support for creating and using Unix domain
sockets from within Pony programs. In particular, this RFC suggests
adding this support to the `net` package.

Using ASIO directly from Pony code might reduce the
need for changing the runtime code.

Note that we can make use of the `compile_error` directive.
