What would and empty right hand side look like in an ANTLR grammar?
While I've been desperately attempting to stand on my own two feet and
be able to determine a first and follow set from a grammar, I've read
and
have been told that determining these sets only become difficult when
you have an empty production. What would that look like? It may sound
a bit silly but at no time have I ever seen an empty right-hand sides
(conventionally written using the Greek letter epsilon) in an ANTLR
grammar.
Thank you very much for your time,
W.
