timotimo hm, the other day i meant to check if many of the int arrays we serialize would benefit from something like delta encoding 00:55
we already have varint encoding, afaik
at some point when we were talking about the unicode database or something someone brought up a compression/decompression thing for lists of integers that was supposedly very good
was it samcv?
just looking at the 'net right now points me at TurboPFor, which has some simd optimizations and such 01:04

AlexDaniel huh, there's a way to add github labels automatically? 10:15
ah, that comes from issue templates 10:16
hmmm

b2gills lizmat: Array:D is still a :U. That is to say that while :D form only matches definite things, it isn't itself definite. So `Any:D ~~ Any:D` should return `False` for any value of `Any` 18:46
lizmat b2gills: but that implies you cannot use a List.method(List:D:) signature for a method that can also be called on definite Arrays :-( 19:18
m: class A { method a(A:D:) { 42 } }; class B is A { }; dd B.new.a # or does it ? hmmmm 19:20

lizmat .ask pmurias why do you think BINARY_ENDIAN_NATIVE is useless ? nqp f82058fc739db76c0 21:27
yoleaux lizmat: I'll pass your message to pmurias.

Revert "[moar] Remove useless constant BINARY_ENDIAN_NATIVE"

This reverts commit f82058fc739db76c0be8db1d6bdc6cc1c8bb1618.
We do need BINARY_ENDIAN_NATIVE!		 22:15

lizmat argh, that should have read nqp::const::BINARY_ 22:49

lizmat afk& 23:06
timotimo interesting, python has a proposal for getting a ?. syntax 23:26
not very much like the .? that we have 23:27
jnthn timotimo: What are the proposed semantics? 23:28
timotimo The "None-aware attribute access" operator ?. ("maybe dot") evaluates the complete expression if the left hand side evaluates to a value that is not None
they'll also have ?? and ??= for "return lhs if it's not None, otherwise rhs" and ?[] which will only eval a subscript if the lhs is not noen 23:29
