That gonna piss people right off if they're forced to implement custom .gist/.perl just to dump the guts of an object with custom .new

i'm not happy about that either ... i'd hope .perl is a "best effort" at giving you something you can eval to get the object back

how about we dump it like do { $_ = Foo.new; .a = 1; .b = 2; .c = 3; .d = 4; .self }

Zoffix

timotimo: that's just a more convoluted way to dump a .new, which still doesn't work because in my example attributes aren't `is rw`

15:06

15:06 brrt joined

Zoffix

Maybe dump all attributes like before, but stick a stub before them if there is a custom .new

15:06

So it'd be `Foo.new(…, a => 1, b => 2, c => 3, d => 4)

timotimo

about the "rw" attributes

Zoffix

So it still dies on .EVAL, because we've no idea how the custom `.new` works, but it still shows all the info for debugging aid

and keeps `infix:<eqv>` working

timotimo

that sounds like a good compromise at first glance

15:08

can we somehow get a better error message than just "stub code executed"? … would take an argument, so a word or two there could be nice

I think the default `.perl` for objects should assume the default construction interface, and if you make a custom `new` and you care about round-tripping then it's on you to write a custom `method perl` to go with it

16:03

Alternatively, dump with `.bless` instead of `.new` :)

roast: 4ae2c6a940 | (Zoffix Znet)++ | 2 files
SAP role multi dispatch test

The test relies on side-effects from `where` clauses which is an unsupported feature that works in Rakudo by accident.
I don't immediatelly see a way to rewrite that test to not use side effects from `where`, so shoving it to SAP.

The remaining items are a better impl of sunk `start`, which
jnthn++ promised to do this week as well as de-dynamification
of `$_` variable, which isn't making it to 6.d on language-level, but we cleaned up 6.d spec to allow for its preview implementation in Rakudo under 6.d language.
