not to the same extent. However, for the same reasons then - one might have
a language which doesn't have the same syntax, e.g., it requires some sort
of mode-switch. Rather than have very-large tables that can handle all
combinations (and mostly unused), you could switch lexers/parsers.

Now that I'm thinking of it, I have an application with more than 50
lexers - the syntax highlighting in vile:

But since lexers are adequate for that, they don't need/use yacc.
