Niels Thykier 686721e91f Rewrite some set constructs
The first case is to avoid a creating a list, which is then converted
to a set only to throw away the list again.  Here we can just create
the set right away without a list inbetween.

The second case is "if x in [...]:" is better written as "if x in
{...}:" as sets provides faster "__contains__" (assuming you are on a
"recent enough python3", which britney is).
