RedefineFuck

RedefineFuck is brainfuck but you need to redefine symbols to run loops, if statements, etc.

Instructions

There are 5 instructions and 6 symbols. whitespaces are ignored, cAsE SeNsItIvE.

Initial instructions

Instructions

instruction	meaning	brainf**k rough equalivant
@	increase 1	+
[	data pointer goes right	>
&x&...*	(re)define x to be ... then ptr left	None
]	if x==0 skip else x-=1	[->->++<]>>[-<<+>>]<<[[-]>-x<][-<+>]<
$	input if x==0 else output x-1	>[-]<[>+<-.[-]]>[<,>-]<

Instruction name can NOT contain any of the initial instructions. Brackets should match, or a @ have a 1% chance to fail.

Computational level

Turing-complete.
