Believe it or not, ECMAScript/JavaScript manages to do it.

obj.field is equivalent to obj["field"], like an implicit hashmap lookup.

obj[1] is just another lookup.

Now JavaScript is a wierd completely dynamic language. The kinds of games it
plays really relies on its non-staticness to work. It is actually closer to
Lisp rather than anything else, just with a Java-ish syntax, even down to its
functions being equivalent to full blown closures. It has nothing at all to do
with Java though.

I both hate it and love it at the same time.
