in reply to Re^7: How does Math::GMP overload the assignment operator ? (more guessing)
in thread How does Math::GMP overload the assignment operator ?
one possibility is to first convert the object to a string and then use the builtin string->number conversion
Yes, that seems consistent with the behaviour I've noticed.
In the absence of a specified '0+' overload subroutine, $array[Math::GMPz->new(-2)] would be stringified to $array["-2"] and then numified to $array[-2]
