In Go 1.8
I'm just wondering if there has been discussions about having "go generate"
tool support a "-parallel n" flag such that it would run go generate on
each file concurrently throughout a package(s). The motivation is this: a
typical build process that involves file generation may need to support th

Hi
As far as the docs are right:
For Back: Back returns the last element of list l or nil.
For PushBack: PushBack inserts a new element e with value v at the back of
list l and returns e.
So if you push nil, you get nil otherwise you get always your pushed element.

Good point. We actually do have quite a lot of code that does copy
everything from one step of computation to next one, for clarity and
separation of concerns.
We're not afraid to do it one more time if needed, i.e. translating all
fundamental Vertices to some "VerticesWithID", and then back.
Thank you Sébastien, I may use some of it (Orientation, etc) in the
project. Having a Point.ID is the straightforwardest way to go anyway.

FTR, I don't think ordering by pointer (no matter whether using unsafe or
not) is reliable and safe. The GC is free to move data around at any point,
including during your sort.
I don't think there are a lot of ways around that. You could basically
build your own allocator and add a way for it to r
In that case, maybe use *Triangle pointers instead of Triangle values, and let

That's actually a clever idea, I had not thought of that when dismissing

But it turns out that X,Y,Z will change often during my program execution:
vertices move, but their identity (and the triangles identity) must be
strongly preserved.
