Hanging else, possible solution #3

[Nino Porcino]

on the GOLD documentation, two ways are reported for solving the hanging-else problem, but I think I've found a third one that includes no extra rule creation. For a C-like language it's like this:

<If> ::= 'if' '(' <Expr> ')' <Stm> <ElseBranch>
<ElseBranch> ::= 'else' <Stm> |  

What do you think about it? Does it behave correctly? I'm currently using it in my compiler and it seems to work as expected.

To which `if' does the `else' bind in `if ... if ... else'?

I'll have to take a closer look at that solution next week. Thanks for your help! ... and I'm AMAZED that someone actually looked at the documentation!  :-)
