newRPL: Named subroutines proposal

[Helix]

I don't like the fact that this syntax breaks the RPL logic (arguments first, followed by the function).
Furthermore, since comments will be possible in newRPL, I don't see much difference with this version of your example:

Code:

<<
      @ ADDTWO SUBROUTINE
      << 2 + >> 'ADDTWO' LSTO

      @ MAIN PROGRAM
      1234 ADDTWO
>>
