Have you proposed some way to do away with default constructibility somehow?
Foo default_foo; Foo foo = lexical_cast(str, default_foo);
(or whatever instead of lexical_cast) has no Foo::Foo() requirement.
and... how is lexical_cast going to come up with an object into which it can stream? Is it going to use default_foo? In that case, what if streaming fails partway through? Are you assuming copyability? -- Dave Abrahams BoostPro Computing http://www.boostpro.com
