Re: [PATCH] Named symbol references

[Akim Demaille]

Too eager to play with your patch, I made several errors in my  
grammar.  I had a $from.name_get() but I forgot to declare [from].   
Bison answered:

ugrammar-pruned.y:534.37-50: reference is invalid: `$from.name_get',  
symbol not found

IMHO it should refer to $from, not to $from.name_get.

Also, I had a $9foo, where 9 should have been removed.  It accepted $9  
and left the "foo" attached to the expansion of $9.  Now that we have $ 
[] to make what we mean clear, I think that it should complain about  
$9foo, like it does for the grammar symbol 9foo.  We should support  
$[9]foo for those who really mean that.

This applies to other values of 9 and foo :)
