nsACString::const_iterator A,B,C;
searchable.BeginReading(A);
searchable.EndReading(C);

while (B != C) ++B;

ok, so what we have here is some condensed buggy code.

anyone who isn't the author or compiler will read it and quickly note that B is never initialized.

What I'm asking for is a debug warning/assert to complain about the use of an uninitialized iterator.
QA Contact: scc → string
char* is the new iterator and the compiler can warn about that one. WONTFIX.
