<snip>
Deremer and Penello describe a method for how you can give a hit to
the user on what is wrong in their TOPLAS article on how to calculate
LALR(1) lookahead sets.
</snip>


Is Deremer's work being used in popular compiler compilers. Also seems
that his tecnique is not quite correct. A paper by Bermudez and
Schimpf on "On the (non-) relationship between SLR(1) and NQLALR(1)
grammars" disproves the claim of Deremer, that says NQLALR(1) is
superset of SLR(1). In the above views, should one use their method?
