+[Jost Boekemeier has suggested the following alternative solution:
+ Commands are bindings just like any other binding.  It is enough if
+ some modules carry command bindings (it's in fact enough if *one*
+ module has them), because from such a module you can use the command
+ (in MODULE) to walk into a module not carrying command bindings, and

+ However, this has the disadvantage of mixing the "real" bindings with
+ command bindings (the module might want to use "in" for other
+ purposes), that CTRL-D could cause problems since for some channels
+ CTRL-D might close down the connection, and that using one type of
+ command ("in") to go "into" the module and another (CTRL-D) to "exit"
