This is indeed something missing in Camlp5. It will be fixed in next
release. In the meantime, you can edit the file "etc/pr_o.ml" and around
line 1100, change:
        <:expr< let $flag:_$ $list:_$ in $_$ >> |
        <:expr< match $_$ with [ $list:_$ ] >> |
into:
        <:expr< let $flag:_$ $list:_$ in $_$ >> |
        <:expr< let module $uid:_$ = $_$ in $_$ >> |
        <:expr< match $_$ with [ $list:_$ ] >> |

(i.e. insert the line with "let module" between the other two)

camlp5: bug?

[Dmitri Boulytchev]

    Sorry if this submission is irrelevant to the list, but I failed to
locate
more appropriate place for it.

    Given the file t.ml with the single line

                    () (let module X = Y in ())

   camlp5 behaves as shown below:

                   camlp5o t.ml >  /dev/null ---- ok
                   camlp5o pr_o.cmo t.ml > /dev/null --- Failure: unable
to print expr
