Sorry if that's missing the point, but I'm currently using something
like the following in my async:// experiments:
-- snip --
async-handler: context [
; default error handler
on-error: func [ port [port!] error [error!] ] [
print mold disarm error
true
]
; default async event handlers
on-connect: func [ port [port!] ] [ false ]
on-close: func [ port [port!] ] [ attempt [ close port ] true ]
on-read: func [ port [port!] ] [ false ]
on-write: func [ port [port!] ] [ false ]
; default dispatcher
handle: func [ port [port!] state [word! error!] ] [
either error? state [
on-error port state
] [
switch state [
connect [ on-connect port ]
close [ on-close port ]
read [ on-read port ]
write [ on-write port ]
]
]
]
]
-- snap --
The 'handle dispatcher is to smoothly use object!'s based on the above
as 'awake handler.
