No. That was documented in the Spirit docs. The problem
is that the comma operator has a very low precedence. even
lower than the =.

I quote:

"N[1] The comma operator as in a, b seems to be a better 
candidate, syntax-wise. But then the problem is with its 
precedence. It has the lowest precedence in C/C++, 
which makes it virtually useless."

I  always wished I could use the comma. I did, initially.
But I got bitten when I typed in:

r = a, b | c;
