Hm. You might have a point here, but then again, you might not.
I'm not convinced that examples of syntactic innovation cannot
be found. I can't think of any, but that doesn't mean they
are not there, waiting to be found. Manifestly, language syntax
does change with time.

Well, I'm not sure anyone said that, specifically... I just think
that ambiguity per se should not necessarily be construed
as some kind of error or obstacle. I personally am not distinguishing
cleanly between syntax and semantics, and I think that this
is an apprpriate point of view. (But I am naive and ill-informed,
so you can ignore me.)
Ambiguity makes things hard to parse, but I don't care,
because I'm not writing a parser. :)
Take the following example:
1) Happy dog, dog fast.
2) Dog run run run!
3) Happy fish, fish fast.
4) Fish swim swim swim!
