XXX = gather {
YYY
take f();
ZZZ
}
sub f () {
return want.Scalar ?? 42 !! 54;
}
Which of XXX, YYY, and ZZZ influence whether the taken value is 42 or
54? Please confirm there's *no way* that &f is entered twice here :-)
(If I'm following correctly, then take's args are basically evaluated
in list context. If YYY is something like "$scalar = " that list gets
Captured, but there's still a list there.)
