This naturally ties in to iteration-limited array iteration. To express this in
the language, one way is to extend the grammar in a way reminiscent of SQL:
foreach ([i1,i2] in ray limit N) {
}
where N is a numeric expression evaluated at the beginning, and doesn't need to
be a literal. The sorting +/- directives would stay as/where they are with
current rules.
How does the runtime sortn compare with sort for N approaching the map size?
