I guess you missed an attachment, or it was too big, or something...

Some objects that might be useful:

[route]

[list prepend]

[list trim]

[pack]

[unpack]


I like the following idiom in abstractions:

[inlet]
  |
[route $1]
  |      |
  |     [outlet]   // pass through everything not for us
  |
message for us

Then you can do something like:

"foo 1, bar 23, baz 99"
  |
[abs foo]
  |
[abs bar]
  |
[abs baz]
  |
...

Hopefully these hints are enough,
