[swift-dev] This little program currently compiles fine, but should it?

[Johan Jensen]

Because currently only unused variable/constant declarations have
warnings/fix-its attached to them.
There have been some discussion on making non-void functions warn of unused
results
<https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20151207/001580.html>
and it’s possible that this would be in style with that.
Perhaps (basically) empty statements should also give a warning?
