[Message part 1 (text/plain, inline)]
Yes this was pointed out to me :-)

Looks like we get the unused variable warning when there is a result form which does not contain the loop variable.

[I guess the normal use case would indeed be to use the loop var in the result form and so writing it like this was probably a reasonable compromise…]

I will adjust my code to work around it.

Thanks,
Mike
