=head2 eval/die remains perfectly workable
Perl5 has a perfectly agile exception handling method,
C, which syntax-checks at compile time and
returns the value of the value of the last expression
evaluated and sets the special error variables in cases
of errors.
We leave that alone, and use it f
or AUTOLOAD can be defined in terms of C
and overloaded that way, rather than being its own
kind of magic.
catch "AUTOLOAD-$classname-$polymorphicsignature" {...

Make them all writable, then we can make user-defined errors seem
to be whatever we want.
Or leave them the hell alone and introduce a new var

Does it allow not only die but everything w/in Carp.pm to be
implemented in terms of it?
