Hmm but I find ‘foreign’ as a substantive hard to parse. :-) The object type in question is now called ‘pointer’ (it used to be ‘foreign’), hence the name. “Pointer” is meant as a synonym for ‘void *’ ans pointer objects are untyped, which may be why it seems “vague”. But hey, the concept of pointing to the void *is* vague. :-) Thanks for the suggestions! Ludo’.
