Hi Erik, the +Agent class in question makes use of rd and pr in combination
with asynchronously connecting to multiple external services, like this:
(dm eval> (A . @)
(let? Sock (sock> This A)
(when Sock
(out Sock (pr (rest)))
(prog1
(in Sock (rd))
(close> This Sock)))))
(dm evalAll> @
(let Result
(make
(for N (getSockNums> This)
(later (chain (cons "void"))
(eval> This N (rest)))))
(wait 5000 (not (memq "void" Result)))
Result))
