a good example might be Ptr Char. Is this a single location of a 32bit / utf32 code point, or an array of utf8 code points or utf32 code points? is it null terminated vs there being an extra sequence length? These are all valid things that can be happening. And
I'm not sure if it affects your point, but I sure hope a 'Ptr Char' points to a 4 byte haskell Char as it claims, and 'Ptr CChar' points to a 1 byte C char, as it claims. Otherwise, sizeOf will be wrong and array indexing will go out of bounds. Of course, in the C case, whether or not there are further chars after that and if they are terminated and what is the encoding is all ambiguous, as it always is for C.
