yes. the expression (display "test") evaluates to the value
#!unspecific.  printing to the standard output is a side effect, not the
value returned by the expression.

in geiser it also "works".  the standard output should appear in a
buffer called *Geiser dbg*.  for guile for instance, it has the
appearance:

   (display "foo")

   => #<unspecified>

   foo

but it seems stdout is not fully implemented for MIT, and that's why you
don't see it.
