Better implementation idea

A. A role "X-no-trace" to compose into any exception class,
B. which at BEGIN installs into the outermost scope CATCH block for
anything that does X-no-trace,
C. 3-6 as before :-)

that way, no need for COMPOSE block and $?CLASS variable. And as a bonus,
can add the X-no-trace to a particular exception, without having to create
a custom exception class-
    die X::IO::DoesNotExist.new(:path("foo/bar"), :trying("zombie copy"))
but X-no-trace;
