Andy,

Based_on for select and enumeration should be implicitly interfaced. If it
doesn't say so under clause 11 then there is a problem there which should be
fixed.

Subject: [wg11] Extending enumeration datatypes and implicit interfacing


Does the based-on datatype of an enumeration get implicitly interfaced when
the enumeration datatype which references it gets interfaced? Clause 11 of
the standard makes no statement that it does, which implies that no implicit
interfacing happens.

The based-on type for select datatypes is implicitly interfaced. This
produces an inconsistency between the two uses of based-on, which seems
surprising.

    thanks
        Andy.
