Why?
He's convinced that it's caused problems for C++ and was a
major mistake. You
can search the newsgroup for discussions on it. The most
recent one which
involved Andrei was in the beta group:

An important smoking gun is C++'s min(), which is allows
writing unsafe code without casts.
const int& haveANiceDay = min(4, 5);

But that example actually works correctly.
TBH, most of the "unsafe" code I have been presented regarding
the implict "cast + ref problem" comes from msvc accepting code
which is not actually legal C++.
In "legit" C++, you *can't* bind a rvalue to a (non const) ref.
gcc will turn you down if you tried any of those "unsafe"
examples.
