I only wonder, have not languages designers become cleverer in the
recent decades to invent languages that do not require the full
strength of LR(k)?


Could anyone show the samples from practical languages
a) where SLR(k), LALR(k) is not enough, well, at least for k<=2, and
b) where this need cannot be reduced at least to LALR(1) by cosmetic
improvements of the syntax (e.g. insertion of anchoring keywords or
symbols)?


Thanks,
Vit
