run-once code

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 (or,
at least, be jumped around). How would I do that in Perl 6?
(I recall seeing something about how to make assertions drop out, but
I want to be able to do this at run-time, not compile-time.)
