[plt-scheme] shouldn't this work?
This top-level begin form splicing does not seem to be working (with 360
nor 369.8):

reference to undefined identifier: x

y = blah

blah
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.
