Ok, I will fess up.
I was really thinking that collections like linked lists, queues, rings, ....
where it would be nice if there was a lib you could import, which hoisted lib
procs (applied by iteration thru each element),
something like
```
import queues, math
import hoisting
hoistLibProcs("queues", "math") # <- this would make procs from math work
with queues
var q: Queue
#
# do setup of queue data here
#
let sq = q.sqrt() # this would take the sqrt() for each element of q (because
sqrt() has been hoisted)
```
Advantages:
* users choice as to whether hoist proc from a lib (can hard-wire their own if
they want to)
* don't have to go through enumerating procs from a lib (matches future changes
in hoisted lib)
* apply to any collection type provided there is a standard collection iterator
(??)
