 - N: yes
 - N: the equivalent of the major 3 types that we use today look like:
 
-    &fn(S) becomes fn(S) -> T
-    @fn(S) -> T becomes @proc(S) (or else a trait)
-    ~fn(S) -> T becomes proc:Owned(S) -> T

 - P: niko and I came to almost the same design. the basic issue is that ... I don't think we'd need proc except that the difference between capture-by-ref and by-val is important sometimes.
 - P: now that niko has brought it up, the fact that &fn captures by ref and ~fn captures by val is kinda weird in the first place, now that I think of it.

 - N: you have to pass them around linearly
 - G: somewhat similar to the old `prog` notion we had way back, which were the spawnable-things. we switched to spawnable functions when we added destructors.

 - P: do we want to continue to infer sigils?
 - N: that's what we're talking about, really. There won't be sigils. So this is about inferring proc-ness
