New parsing possibilities

[dunbarx at aol.com]

I had started something trivial on the forum that has become very interesting. Not sure how many here also lurk there, so I thought I would bring it over.


Originally, I had commented that something like:


if x,y,z = 0 then beep


threw no error. That has evolved quite nicely into a parsing discussion, and it is worth looking at. It is currently at a stage where new capabilities are being discovered, since:


put 2*2,3*3=4,9  -- returns "true", or
put 2*2,3*3 --yields "4,9".


There are undocumented rules here, for example:


put 2*2,3*3,(0=0) -- yields "4,9,true"


whereas


put 2*2,3*3,0=0  -- yields "false"


Implying that the comma delimited list is parsed as "2*2,3*3,0" = "0" and not as '2*2,3*3,0=0" yields some value as in the first case. Not sure how useful this all might be, but that is what they said about electricity.
