[go-nuts] Idiomatic Arrays?

What is the idiomatic way to create a list that I'm uncertain of what the
end size will be and fill it with structs?

I'm a bit lost as to what the best way to do this is, and I have a a
feeling that "container/list" is a bit overkill.

But also, having an empty array and then continuing to append one struct
after another in my for loop seems to be not the best way either.

Thoughts?
