Special bits

• If nothing is printed during the run of the program, the whole stack will be joined together (stringified, with values less than 10 or greater than 256 being treated as integers) and printed

• Closing brackets can be left out of programs, and will be auto-completed in a LIFO matter

• There is also implicit input. If you use ^ and : on an empty stack, one line of input will be taken.

• The next edit of the interpreter does not have -1's being pushed to the input.
