I've recently started using DustMite to reduce compiler errors

is nightmarish to reduce by hand.
Two questions:
1. What exactly does unwrap (as opposed to remove) do?
Unwrap is a reduction operation which tries replacing a node with
its children. It will remove redundant parens and braces, for
example.
2. When there are multiple imports in a single statement, i.e.
"import foo, bar;", does DustMite try to get rid of individual
ones without deleting the whole statement?
Yes, but it can't remove the first (or the last, I forgot) item
in a comma-separated list. This is because the internal
representation has no notions of token-separated lists. It's a
long-standing complicated problem.
Is this what unwrap does?
No.
