It's not my intent to dissuade you from contributing to PLT Scheme,  
but I would caution you against lumping Smalltalk in with languages  
like Java and C++; Smalltalk is the "real" OO (cf. Matthias' talk),  
and includes most of the features you'd expect to find in a functional  
language. In fact, Smalltalk's syntax for introducing a closure is  
lighter-weight than Scheme's, and allows a fairly natural-looking if  
that's a function rather than a special form.  Honestly, calling a  
language "OO" doesn't really mean much, these days (cf. Shriram's  
"post-linnean" stuff).
