I occassionally hit this bug, but it's pretty easy to spot after I introduced it a couple of times. Allocations in Go are slow enough that I usually do this by default unless I know that performance absolutely will never be critical (e.g., doing CLI boilerplate that just needs to be fast on human timescales).
