nine lizmat: apparently those inlining tests also fail in my development environment, which is good, as I can have a closer look. And indeed, I get # Failed test 'Was AT-KEY inlined?' at t/09-moar/11-inline-hash-key.t line 15 when the inline report lists "2x unspecialized AT-KEY BB(7867, 270 bytes) -> postcircumfix:<{ }> BB(2490)" in the successful inlines 09:07

Add BB.specialized attribute, fix name checking

Apparently a BB can be inlined *without* it being specializd, and that is reported in the log. Unfortunately, this wasn't taken into account when looking for names, so name checks (like the t/09-moar/*inline*.t tests) would report failure, when in fact the name checked for *was* inlined, but without being specialized.

MasterDuke at HEAD of master/master/master i still get some inline test fails (t/09-moar/14-inline-comparators-str.t) with no other system load. with moarvm on my always_log_decont branch (rebased to HEAD of master) i get a bunch of additional inline test fails 10:11

nine When it does succeed, it's: 2x infix:<eq> BB(4786, 68 bytes) -> abs2rel BB(12041) 13:40

lizmat I think the BB numbers check out actually now
hmmm... perhaps I should make each op test in a separate sub and have it check the name of the BB inlined into? 13:46
13:48 cog__ left
nine That wouldn't fix that infix:<eq> just doesn't get inlined in this case 13:51

Fix for #4216

It turned out that a lazy iterable as part of a non lazy list of indexes in a slice, had the possibility of hanging because eager semantics where being used on the lazy iterator, e.g. in `(1..10)[1,^Inf]`
This commit removes all of the Array::Slice classes that existed for ... (20 more lines)

Geth roast: 187d894660 | (Elizabeth Mattijsen)++ | S09-subscript/slice.t
Mark failing test as todo for now

The semantics of a lazy list slipped into indexes of an array slice, appear to be assuming that the laziness of the Slip would actually influence the laziness of the outer sequence. I don't believe this to be sane semantics.
See: github.com/rakudo/rakudo/commit/5eeddd37fa
