I think the warning would be useful if it doesn't trigger a lot of false
positives. I feel like it wouldn't today. When I was grep'ing for
'release ()' I only focused on the calls that weren't assigning a value
to a result and I feel like there weren't many of those (and some were
assigning, just not obvious in the one line of grep context).
