	-- \| This module contains some approach for emulating array syntax from
	-- imperative languages. The approach emulates only syntax, not efficiency.
	-- Though if you like working with persistent arrays it may be good for you.
	-- Also it's a fun exercise on lenses.

	-- To run:
	-- cabal repl -b pretty-simple
	--
	-- Colorizing and pretty-printing ghci output
	-- requires: pretty-simple
	:set -interactive-print=Text.Pretty.Simple.pPrint

	-- green bold lambdas and multiline mode
	:set prompt "\ESC[1;32mλ: \ESC[m"
	:set prompt-cont "\ESC[1;32mλ\| \ESC[m"
