FWIW, consider first that :
if false {
foo()
bar()
}
is legal (and sometimes recommended by autorities, as opposed to
momentarily commenting out a block, and struggling with unused vars);
and second that :
func log(msg string, level uint) {
if level < appLevel {
triggerBigNetworkLogTool(msg)
}
}
is legal and useful, even if appLevel happens to be a uint constant with
value 0. See https://play.golang.org/p/nGbELUdvvu
The current policy seems to be: a unused variable is always regarded as a
compilation error, but unreachable code (dead code) is never a compilation
error.
