Stupid Worm Languag

program space is an arbitrary sized grid of bytes
the worm starts as just a head @
as it passes over commands, they get moved to the back of the worm
values get pushed to stack (eaten) when passed over, worm body length increases
the program gets rearranged every time the worm executes it

commands

+- pop 2 values, push sum/difference (uses the order they are popped, so `0-` negates the top of the stack)
><^v change direction
0..9 push number to stack
/\ pop stack, reflect to the side if not zero
? reads one byte of input
= duplicate top of stack
! pop and write output as ascii char
" pop and write output as number
_ push a space character
all other characters are pushed as-is
