I suggest that you do not: Joel is already planning to work on this,
that would be duplicate work.
It is only duplicate work, if they implement the same version of LR
(1). What
version will he be implementing?
I haven't decided yet. Moreover, I think it would be better for
Bison to
have one LR(1) implementation and, say, XML output than to have two
LR(1)
implementations.
If there is a choice. And which variation of LR(1) would you prefer,
if there now is a difference: One that compacts the states and still
has the same problem as LALR(1) that when an error token comes by,
some actions can be performed before the error is being reported plus
it cannot be used in interactive scanners to report possible token
completions, or one that does not have those flaws, but takes up
perhaps much more space?
