[antlr-interest] Reg LR-style expression parsing in wiki

[Gokulakannan Somasundaram]

Hi,
   I was looking at the wiki page
http://www.antlr.org/wiki/display/~admin/2008/03/23/Faster+expression+parsing+for+ANTLR
   The syntax suggested seems to have left recursion.  Can someone clarify
me on that?
   I am really getting curious with the techniques followed in parsing
thanks to ANTLR community.

Thanks,
Gokul.
