Checked-dereference conditions

by Eelis van der Weegen


This is a proposal to add a new form of condition...

For example,  if (T x : e) s  translates to  if (auto && __p = e) { T x = *__p; s }  for some invisible name __p.

Translation for the new form of condition in a while or for loop is analogous.

The "next generation" version where the type defaults to auto && is also proposed.
