-  discard_const.
-
-  It also means that other error types aren't as swamped by the noise
-  of hundreds of const warnings, so we are more likely to notice when
-  we get new errors.
-
-  Please only add more uses of this macro when you find it
-  _really_ hard to fix const warnings. Our aim is to eventually use
-  this function in only a very few places.
-
-  Also, please call this via the discard_const_p() macro interface, as that
