What would these do?
while =$IN -> $l1,$l2 {...}
while =$IN -> @x {...}
That first one seems particularly useful. I'm not exactly sure what
the second one should do, but it seems like it should be similar to
{ my @x = $IN.slurp; ... }
Can it be that unary = in n-ary context iterates like p5's <> except
when n == Inf or n == 0 (which are list and void context I guess) ?
