[antlr-interest] Local lookahead depth

[Oliver Zeigermann]

Another nice feature of LLK

http://llk.sourceforge.net

is that it allows to specify lookahead depth locally per block. This 
allows for more efficient parsing as only for the rules that need deep 
lookahead this code is generated.

Also nice!
