Internally, it is significant. But from the user perspective the focus still remains on high compatibility.

It would be best if NewRPL could suggest the appropriate change when encountering the original syntax, as most folks will no doubt simply try to feed existing code to NewRPL without manually pre-screening and modifying the code first.

I think you are bringing a good idea to the table. Perhaps instead of trying to have compatibility by brute-force, by creating dummy commands like AXL, etc. or affecting performance by converting lists to matrices, the simulator should include an option to load source code from classic RPL and do an automatic translation to newRPL (or, as you suggest, simply analyze the code and provide suggestions to the user in a code editor with syntax highlighting, etc). The changes would be relatively small: removing the dots after the numbers, for example, and changing symbolic lists of lists into matrices. But that converter should be either a separate application or an option in the simulator, rather than having the newRPL core trying to keep compatibility during runtime on-calc.
