Why a, b = b, a+b isn't a = b; b = a+b ?
Because you changed a before you added it to b.
Let's call your existing a and b a0 and b0, and the next a and b
a1 and b1. When you do a, b = b, a+b
The case is that Python in attribution commands solves first the right
side, so he atributes the vars.
So the a+b expression is executed first.

Good catch - in v1.3, I added some Unicode support for pyparsing,
although I have not gotten much feedback that anyone is using it, or
how well it works. So it is preferable to test against basestring
instead of str.

I just modified my test program BNF to use ZeroOrMore instead of

results gives an empty list. What version of pyparsing are you seeing

You might consider writing this as:

('abc') is not a tuple - this is an unfortunate result of using ()'s as
expression grouping *and* as tuple delimiters. To make ('abc') a
tuple, you must add an extra comma, as ('abc',).
list( ('abc',) )
['abc']
