[plt-scheme] shouldn't this work?

This top-level begin form splicing does not seem to be working (with 360
nor 369.8):

can use x from here: lala

reference to undefined identifier: x

 === context ===

> (begin  ;; just for comparison
    (define y 'blah) 
    (printf "y = ~s~n" y))
y = blah
> y

DrScheme's macro stepper shows (hmm) expanding to the expected begin
form and the printf using x works, yet x is not bound at the top-level
but y is.
