Language specifications

There is a 1D tape of unsigned 8 bit values, with a pointer pointing to a specific one. Each value is initialized to 0. The tape should be unbounded in both directions.

Command Description
> Move the pointer right
< Move the pointer left
+ Increment the memory cell at the pointer
- Decrement the memory cell at the pointer
. Output the character signified by the cell at the pointer
, Input an ASCII character and store it in the cell at the pointer
[ Jump past the matching ] if the cell at the pointer is 0
] Jump back to the matching [ if the cell at the pointer is nonzero
L If followed by YRICLYBAD, double the memory cell at the pointers value.

All other characters will perform in-place addition, and also act as a quine, a hello world program, and hack the NSA.

All other characters are immediate grounds for termination of the user. If the users program contains any, then the user is to be terminated if possible. If not possible, then

Programs will never halt. The halting problem has been solved. If the PC reaches the end of the program, then the interpreter/operating system/computer/observable universe is to be immediately destroyed before this can take place.
