It doesn't, but if your Scheme has an "eval", you might be able to do
something like this [leaving out the 2nd arg to "eval" in older Schemes]:

	> (define (load/value fname)
	    (with-input-from-file fname
	      (lambda ()
		(let loop ((sexpr (read))
			   (result #f))
		  (if (eof-object? sexpr)
		    result
		    (loop (read) (eval sexpr (interaction-environment))))))))

	> (load/value "blub.scm")
	42
	>
