Folks, this discussion seems to be spinning. All the points, on both
sides, have been made and are being repeated with only slight
variation. We've all made our cases--why don't we drop the issue for
a while and let Larry ruminate? I think we can all agree that he will
give the idea a fair heari

Very top row, one space right of the F12 key. Extremely awkward.

Given this code:
if ( some_expensive_lookup_function() >= $MAX_RECORDS ) {
mark_that_we_have_reached_max_records();
return;
}
After I enter that block once, I never want to evaluate the condition
again--I want the code to completely disappear from the bytecode (
