Re: [julia-users] "shrink wrap" overallocations?
I've labelled that as "up for grabs" and "intro" since it should be pretty straightforward to do.

Ah, yes - it's coming full-circle. https://github.com/JuliaLang/julia/issues/2879 - I must have subconsciously remembered your use of the term "shrink wrap".

Re: [julia-users] "shrink wrap" overallocations?
I don't think we have an API for this – I would suggest that sizehint!(c,n) where n is smaller than the current size of the collection c should do this, if someone wants to take a crack at it.

[julia-users] "shrink wrap" overallocations?
Inspired by a discussion here: https://github.com/JuliaLang/julia/issues/14112#issuecomment-159715454, it might be nice to be able to reduce the amount of "padded" (allocated-but-not-yet-used) memory for dynamic structures in certain cases where we're not planning to expand the structures significantly (and can tolerate allocation delays if we do). Does a function that does something like this exist already?
