[antlr-interest] Javascript virtual semicolons

[shmuel siegel]

Javascript 1.5, or whatever you want to call it, has a very strange 
lexical rule:
If the parser ran out of alternative for the last token, back off, 
insert a virtual semicolon and try again. If this works, continue, else 
raise an error condition.
How do you do this in antlr?

Earlier versions of javascript have a more complicated definition of 
virtual semicolon but still do the same sort of thing.
