(help) vs ,describe

[Daniel Llorens]

(help) doesn't seem to work for procedures defined in the REPL.

scheme@(guile-user)> (define (hello x) "hello for x" x)

scheme@(guile-user)> (procedure-properties hello)
$1 = ((arity 1 0 #f) (name . hello) (documentation . "hello for x"))

scheme@(guile-user)> ,describe hello
hello for x

scheme@(guile-user)> (help hello)
Did not find any object named `hello'

It doesn't work either if I use scm_set_procedure_property_x() from C 
(,describe does work).

Why is this?

Thanks,

        Daniel
