A programmer should not expect alignof to return the number of bytes in a
char array. If I'm understanding what you're suggesting correctly. I'm a
little confused.

Subject: [std-proposals] operator alignof





class cstring {

  // assume public functions...



  char* ptr; // used for dynamic allocation

  uint64_t length;



Now, assume I make cstring c("12")


Length takes 8 bytes.

Allocated char array takes 3 bytes.



returns 8


Why not 3?:


// In cstring

operator alignof () {

  return alignof (charArr);



Which is what the user expected!
