I'll bet: in order to be LR(\infty) equivalent, it has to keep the whole stream of tokens available for traversal in both directions. Be it so: this isn't the age of 640K any more. > [2]: Actually, without an extension to PEGs, 'zoi' cannot be handled > without a pre-processor, and without a re-definition that is at least > marginally sane, 'sa' doesn't even have a working definition to try to > handle. The definition of "sa" is straightforward: check the selma'o of the next token rightward, and remove tokens leftward until a token of the same selma'o has been removed (in the usual extended sense of "selma'o"). > [3]: OK, well, I *could* replicate current behaviour, but as current > behaviour is based on the technical limitations of YACC and does not, > for example, resemble what is described in the book, why would I do > that? By all means. All of this stuff is *extremely* borderline behavior.
