When the game blocks e.g. "ENTER CHURCH" it doesn't block "GO TO CHURCH"

Rockvil changes over time, e.g. after 2041 the Train Station turns into the Church Lobby. To keep the player from refering to the church, CHURCH-OBJECT does this:

     <COND (<AND <EQUAL? ,HERE ,TRAIN-STATION ,BODANSKI-SQUARE
                       ,MIDLAND-AND-RIVER>
             <EQUAL? ,SYEAR 2041>
             <NOT <MOBY-VERB?>>>
        <CANT-SEE ,CHURCH-OBJECT>)

This works fairly well, but is not airtight:

>LOOK
Bodanski Square
This is a large plaza formed by the intersection of Bodanski Boulevard from the
east, Centre Street from the southwest, and River Street from the north and
south. There is a car lot on the western side of the square. On the northeastern
corner is a restaurant, and the old train station can be entered to the
southeast. A covered stairway leads down to the Tubes.
There is a newspaper dispenser chained to a lamp post on the corner.

>EXAMINE CHURCH
[You can't see any church here.]

>ENTER CHURCH
[You can't see any church here.]

>GO TO CHURCH
Train Station
The former North Central Station is a magnificent building from the earliest
part of the twentieth century. Unused for years, it has been restored as a
national landmark. The newsstands have been converted to souvenir stands, and
tourists stream through the station to buy tickets for a fifteen minute ride on
an authentic electric railroad train, which can be boarded to the east. You can
leave the station to the northwest or southwest.

That's because MOBY-VERB?, through PRSO-VERB?, explicitly allows the WALK-TO action.

I'm a bit scared of changing that though, since I don't know what unwanted effects that might have. So perhaps we should just allow it?
