I'd retitle while queuing, as the last 'type' is a placeholder for
concrete types like <type> above.

Splitting these into two lines (unlike placing on a single same
line, which was how the previous round was queued) like this is
good.

But this is wrong, no?  You meant opt->value points at an integer
variable that receives the type we discover by parsing, i.e.

	to_type = opt->value;
