How is it a fatal error? It's effectively a semi-static variable, but I don't see any error checking code.

I would have expected something like croak( 'Cannot call constructor on instance' ) if blessed( $class );, but all I see is mixing a lexical declaration with a postfix conditional, which usually isn't the right thing.
