He means, the exception was not necessary because Perl's builtin-in
functions could have returned '0E0' instead of '0 but true'.  Both convert
to 0, both are true in a boolean context, but '0E0' is numeric and '0 but
true' isn't.

If Perl's built-ins had been written to return '0E0' instead, then there
would not have been an exception for '0 but true'.
