Yeah, would be nice if that was mentioned somewhere.

in the section of the docs where:
s[] = 3;		// same as s[0] = 3, s[1] = 3, s[2] = 3

I (naively) expected:

s[] = new C;  // to be same as s[0] = new C, s[1] = new C, s[2] = new C
or
s[] = foo(); // where foo returns an object (a different one each time)

easy to work with and around as is, but would be rather nice to be able to
do what I just stated.  Syntactic sugar for 2.0?
