Kaiepi so a term i see a lot in Perl6::Actions and Perl6::Optimizer is "lowered". what exactly does this mean? 10:51
a pr i want to make has to do with variables not being lowered when i assume they should be, which i'm assuming isn't a good thing, but that's a lot of assumptions to be making 10:52
10:57 sena_kun joined
timotimo lowered is either a) when instead of a general implementation being called with some options, we generate some code in place of the call or b) what used to be a lexical variable turns into a much cheaper local variable 10:57
i guess you could say something is moved from a "more powerful" to a "less powerful" construct 10:58

Kaiepi the latter i assume would make the pr be worth making then, i think timotimo 11:18
timotimo depends on the circumstances under which they currently are prevented from being lowered 11:21
we have to be careful, since any possibility of accessing a lexical from an inner block or closure means we can not lower it, otherwise it'd be a bug 11:22

Add R:I.ReifiedListReverse

An iterator that produces the elements from a reified list from the end rather than from the beginning.		 11:43
rakudo: 270cc27559 | (Elizabeth Mattijsen)++ | src/core.c/List.pm6
List.reverse now uses R:I.ReifiedListReverse

This saves one (potentially large) IterationBuffer allocation, plus a lot of needless work copying values over.
rakudo: cea0fc78d1 | (Elizabeth Mattijsen)++ | src/core.c/Seq.pm6
Give Seq its own .reverse using R:I.ReifiedListReverse

This bypasses the ordinary List creation with all of its overhead and just create an IterationBuffer directly and then iterate from the end.
timotimo cool 11:46
Geth rakudo: 4025ca4377 | (Elizabeth Mattijsen)++ | src/core.c/Seq.pm6
Make sure Seq.reverse fails on lazy iterators

That was one thing the previous Seq.list.reverse path did do, but now we check without trying to reify.		 12:06

Check reified before sending it off to R:I

Turns out, something in the bowels of the module loader is creating an empty String object without setting the $!reified attribute, and calls .reverse on it. In the old code, this would be caught by the conditional: the new code didn't do that, assuming it would be handled inside R:I. Restored the old situation, but still calling the new ReifiedListReverse iterator.
This fixes test failures as seen in CircleCI and friends.		 16:20

Make Supply.grab a few percent faster

Use an IterationBuffer as the cache, and nqp::push rather than HLL push. Saves 1 Scalar and 1 BOOThash per value emitted.		 19:53
rakudo: 4339073baf | (Elizabeth Mattijsen)++ | src/core.c/Exception.pm6
Use .skip instead of [1..*]

The [1..*] first caches the Seq, then creates a List out of the given indices, and the creates a Seq out of that. .skip just loses one value from the Seq while returning it, so that's much more efficient.		 20:13

rakudo: 33f41966cf | (Elizabeth Mattijsen)++ | src/core.c/Supply-coercers.pm6
Use a smarter semaphore in Supply.squish

Since foo.WHICH can never produce an nqp::null, use nqp::null as a semaphore to indicate the first value has not yet been seen. Removes the need for a native integer (check) for each received value.		 20:54
