the only reason why your output seems to be correct is that you are dereferencing the $vars hash-ref from the closure

Oh!
Yes, changing the variable name in the subroutine 'breaks' it as expected...now I understand why the different bits of seemingly identical code behave differently! Thanks Rolf.

$vars->{'test'}; instead of $$vars{test}

I did have $vars->{'test'}; in there at one point whilst testing it.
Why is this preferable to $$vars{test}?
