Oops! Good point, which emphasises the point about shorter not
necessarily being better!
My personal approach would be two separate comprehensions(*) which
keeps the intent very clear and keeps it short at the expense
of iterating the original list twice.
(*) Or you could use the filter funtion twice if you want to
make the intent even more explicit...
