No. Parsers changing lexers is not advisable because the lexer can be any
number of tokens ahead of the parser since antlr has "infinite" lookahead
capability through syntactic predicates.

Hi,
Can multiple lexers be implemented so that a different
lexer is activated in parser or atleast based on a
rule that matches in parser ?
Thanks
Mark
