Allow code completion for methods that take a callback

[sethladd]

This web socket code:

var ws = new WebSocket("ws://localhost:1337/ws");
ws.on.close.add( /* here try to run code completion */ );

When you try to run code completion inside a method that takes a callback function, you get nothing. :(

It would be very helpful to know you you can pass in a function here, and that the function takes a Dynamic event object.

Thanks!

Added I/O milestone since Seth likes to dream.

Thanks Steve :)

Removed this from the M1 milestone.
Added this to the IO2012 milestone.

Is that sample code correct? My version of WebSocket is quite different. Might be worth adding a bug about cross-library consistency, so that dart:io is similar to dart:html (unless my version is out-of-date).

Yup, this came up again today. I used dart:html for the example in the main description. The way dart:io sets up callbacks in in WebSocket is different. I'll open a bug.

Fixed in build 8808.
The first computer I built was based on the 8088 chip.
