[antlr-interest] do we need "..." and '.' ??

[Akhilesh Mritunjai]

Hi

No, we don't need both. I have not been able to come up with a use case  
for both.

However, in several place we need embedded quotes or double quotes. So it  
might be worthwhile to ponder over making it python like where single  
quotes and double quotes are equivalent when used as string delimiters.
