== Influence ==
== Influence ==
Many of the extensions have been adopted into [[dzaima/APL]], while Dyalog APL added [[Constant]] (<source lang=apl inline>⍨</source>) and introduced non-experimental [[Case Convert|case conversion]] as a <source lang=apl inline>⎕C</source> [[function]] rather than the proposed [[operator]]. Dyalog is also considering adding [[Reverse Compose]], [[From]], and [[Depth (operator)|Depth]].
