Slightly more reduced testcase

It looks like the front-end is getting confused at the 2 z functions; even
though they are in different modules, the front-end seems to have copied the
body of the first one into the second but since the second one uses the result
option which sets up the return value to be named field rather than the
function name things go down hill.
