Quick - ÐL - Repeat Until No Longer Unique
Tags: hyper
Arity: same
The resulting link's arity is the same as the consumed link's arity. Note that the arity refers to that of the resulting link, not the number of links this quick consumes.
Functionality
Repeat a link until the result is no longer unique, returning the last unique result.
Details
If the link is dyadic, after the first iteration, the previous result is the left argument and the result before that (the left argument is the initial result) is the right argument. No-op for niladic links. For example, to evaluate 1 +%10ɗ ÐL 1, we begin with 1. The next value is 1 + 1, then 2 + 1, then 3 + 2, then 5 + 3, then 8 + 5 (which evaluates to 3 because of the % 10). This result is not unique, so the result is 8.
Syntax
<link>ÐL- loop until results are no longer unique
