I don't think that introducing a Pascal-like syntax was a bad idea.
Dropping the Lispy syntax was the bad idea.
In the static language camp, I can happily mix libraries from Fortran,
Pascal, C and C++. If there were interoperability between an infix
and a prefix Lisp-like language, that would be a huge win.

One instance where sealing really helps is arithmetics. Witness Java
for a language that gives up it's OO approach for fast integers, and
the problems this introduces. In Dylan, integers are objects like all
others, still arithmetics is fast, because operations are sealed.

I like the "objects from the grounds up" approach, and Dylan feels
very clean and consistent to me. That couldn't have been achieved by
a couple of libraries.
