00:01 timotimo m: say 19768 / (19768 + 36992)
00:01 camelia rakudo-moar 855de7: OUTPUT«0.348273␤»
00:01 timotimo so about a third of deserialized p6opaque reprdata space used for auto_viv_values have nothing but zeroes in them
00:10 timotimo there's already a flag that says "should the auto_viv_values be grabbed from the serialized blob at all?"
00:10 timotimo a varint
00:10 timotimo it could easily store an extra value that says "build the array out of zeroes, please"
00:11 timotimo that'd save one ref per attribute, which is at least one byte for the descriminator and in this case probably nothing else ... hmm.
00:12 timotimo so the first number above divided by 8?
