[Peter Lewerin] (2004-01-26): Watch this space for an unorthodox, radical, contrastandard, and hopefully interesting variant of Tcl...

The '''>''' is the interpreter prompt;

 (1)
 > 2 3 4
 4 3 2

 (2a)
 > 2 3 4 +
 7 2

 (2b)
 > 2 3 + 4
 7 2

 (3a)
 > 2 3 + ; 4
 4 5

Care to guess?  Should be easy thus far.

[RS]: Should the third example not rather come out as "7 2"? So far this looks most like [Forth] to me...

(PL): Yes, error in transcription on my part, corrected now.  Forth is a good clue, but how about this:

 (3b)
 > 2 + 3 4
 4 5

 (4)
 > + 2 3 4
 error: must have at least one result to work with

 (5)
 > 2
 2
 > + 3 4
 4 5
 > + 3 4
 4 7 5

[RS]: so binary operators work either infix or postfix (RPN), and the stack is returned, top at left?
