1. Allow input of numbers in binary, octal, and hexadecimal. (Does lua natively understand 0b10101, 0o147, and 0x17AF or something similar? That would be nice.
2. Control how the result of the expression is returned with new operators: bin, oct, and hex. These shouldn't change the stack, but just format the returned string a specific way.

Examples:

• 0x1E bin returns 11110. Since the operator only changes they way results are reported, bin could appear anywhere in the expression. bin 0x1E returns the same result.
• Mixed bases should be processed seamlessly. 0x1E 0o55 + returns 75 (in decimal by default.)

• xm - store X in memory
• rm - recall memory to the stack
• m+ - add X to memory
• m- - subtract X from memory
• xy - swap X and Y
• lastx, or maybe just x - put last value of X (from before the last operation) on the stack again
