Influenced by	Dyalog APL, K

RAD stands for Rankless APL Derivative. It is very closely related to APL (mainly the Dyalog variety), but uses K's array model, including the ability to "box" functions and use them as elements of an array. It was created by Zachary Taylor, 3rd place winner of Dyalog Ltd.'s 2017 APL Programming Contest.

RAD adds a few new primitives, among them:

• <source lang=apl inline>μ Arithmetic mean/Mold left like right
• <source lang=apl inline>π Pi
• <source lang=apl inline>" Character↔Integer (<source lang=apl inline>⎕UCS)
• <source lang=apl inline>⍁ Left-to-right version of <source lang=apl inline>/
