RFC: Allow longer binary operators

Hi all,

In the bluebook the length of a binary selector is limited to two, in the ANSI
Smalltalk draft the length is arbitrary. I would like to have some comments of
what needs to be changed and such.

E.g. upstream RBParser was changed to remove the check for the '-' as second
char in the selector and I wonder if I got it wrong...

regards

Thanks for the patch.  However, is there any actual usage of these apart
from PetitParser?

Hi,
I am not sure. One argument for them is that ANSI Smalltalk allows them, I
will try to figure out how to find binary selectors in Pharo and report back.
