[1] The following grammar fragment should give an ambiguity warning
but does not:
c : ( <<p1>>? A | <<p4>>? B | B)* <<p3>>? B
;
[2] ANTLR generates a warning for the following situation, but
it should really be an anachronism meaning "otherwise":
if : "if" expr "then" stat
| . <<fprintf(stderr, "malformed if-statement");>>
;
[3] (..)? in C++ mode do not work yet when using DLG-based scanners.
[4] Token pointers ($i's) are not set properly in -gk demand lookahead
mode when generating C++ output. The infinite line number stuff
won't work either in C++ mode.
[5] Combination of LL(1) AND syntactic AND semantic predicates does
not see to work well.
[6] There is a bug in the predicate context computation so that
"-prc on" ANTLR option may not work.
