+  this is a warning hack. The idea is to use this everywhere that we
+  get the "discarding const" warning from gcc. That doesn't actually
+  fix the problem of course, but it means that when we do get to
+  cleaning them up we can do it by searching the code for
+  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
+  makes the return type safe.
