If we do that, we'll need to have a way to distinguish whether sv_2nv() is being used in an lvalue or rvalue context, or perhaps assume the former and introduce a sv_2nv_force(). (I was assuming that sv_2nv() always forces NVness as it does now, while changing SvNV() to convert only when necessary.) Sarathy gsar@ActiveState.comThread Previous | Thread Next
