Those "omnibus" modules are quite handy, the only downside of "Foreign" is that
it doesn't exactly collect the modules below it in the hierarchy. This would
have been the better choice IMHO, but we decided to do differently for legacy
reasons, IIRC. Renaming "Foreign" will probably wreak havoc, much more than
simply adding 2 functions to "Foreign.Marshal.Array", which get re-exported
by "Foreign".
