It uses a fast but not so space-efficient encoding for the parse
tables, described in Corbett's PhD thesis from Berkeley:

For generating the lookahead sets, Wisent uses the well-known
technique of F. DeRemer and A. Pennello they described in:

+@item
Wisent resolves shift/reduce conflicts using operator precedence and
associativity.

+@item
Parser error recovery is accomplished using rules which match the
special token @code{error}.
@end itemize
Says that two groupings of type @samp{exp}, with a @samp{PLUS} token
in between, can be combined into a larger grouping of type @samp{exp}.

The Wisent's parser doesn't depend on the nature of analyzed input
stream (buffer, string, etc.), and requires that lexical tokens have a
different form (@pxref{Writing a lexer}):
