An APL Quine

APL is a

programming language developed in the 1960s by Kenneth E. Iverson. Its central datatype is the multidimensional array. It uses a large range of special graphic symbols to represent most functions and operators, leading to very concise code. It has been an important influence on the development of concept modeling, spreadsheets, functional programming, and computer math packages. It has also inspired several other programming languages.

I recently started studying APL. An challenging exercise in any language is to make a quine; a program that prints it's own source code.

Below you can find my quine in APL. Now let's hope I can understand it myself after a month or two.
