Ordinarily this would be fine, but for non-C languages it's sometimes
useful to "set lang c" and see what the C type-printer thinks. For
example, in Ada there are "fat pointers" that are really just a kind of
struct. Ada will always print these as ordinary access types, but it
can be handy to look under the hood and see that it's really a struct
type.
Maybe there's some better way to do this kind of thing. Like we could
add "ptype/c" for "C style printing".
Keith> In any case, it LGTM. I recommend you approve your patch.
Thanks.
Tom
