Hi Marcus - does this mean that a fresh zero conf of 6.1 will have the variable undeclared change? If so - then I should remove my port of your fix into what I load into exercism.
This does raise an interesting question - is there a way to get a fixed 6.1 version (like a tag) - so that I don���t always have to retest if stuff gets ported? (e.g. have a known tagged version that will work until I retest with later back ports?)
