Good catch! This allow applies to 'keys' and 'entries' enumeration. I seems to me, that if we want -0 and 0 to act as the same key value, that we need to normalize -0 to 0 when storing it as a map key. SameValue0 remains what we want to use when doing a key lookup, Allen _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
