[17​:44] <pmichaud> bbkr​: it's TODO
[17​:44] <bbkr> pmichaud​: but is it already in RT queue? I cannot find it.
[17​:45] <pmichaud> bbkr​: and I'm not sure that callframe will have a .perl
method anyway
[17​:45] <pmichaud> at least, not something that gives you a complete
serialization of the current call state.
[17​:47] <bbkr> pmichaud​: I can imagine how hard to implement this would be.
but if not - then still error message is LTA.
[17​:47] <pmichaud> why?
[17​:47] <pmichaud> it's exactly correct. :)
[17​:47] <pmichaud> it's saying the .perl method doesn't exist. :)
[17​:51] <masak> :)

[17​:52] <moritz_> adding a method perl() { fail "Can't serialize callframes" }
would be pretty easy too

[17​:52] <bbkr> pmichaud​: because "callframe.WHAT" is "CallFrame"
not "ParrotInterpreter". and CallFrame has .perl method.

[17​:53] <pmichaud> then callframe.perl should work
[17​:53] <pmichaud> does CallFrame have a perl method?
[17​:53] <moritz_> no
[17​:53] <pmichaud> I didn't think so. :)
[17​:53] <pmichaud> bbkr​: why do you claim CallFrame has a .perl method?
[17​:53] <bbkr> rakudo​: CallFrame.new.perl
[17​:53] <p6eval> rakudo 859f2d​: ( no output )
[17​:54] <pmichaud> rakudo​: say callframe.WHAT;
[17​:54] <moritz_> the problem is that callframes can be asked for any
information in caller frammes

[17​:54] <pmichaud> okay, I'll accept that the error message is wrong here.
[17​:55] * bbkr reports LTA message in callframe.perl

From @bbkr

[17​:57] <pmichaud> why are we getting a ParrotInterpret...... oh, I see
the problem.
[17​:57] <pmichaud> The problem isn't with CallFrame.perl, it's with
CallFrame's $!inter.perl
[17​:57] <pmichaud> $!interp.perl
[17​:57] <pmichaud> the default .perl is attempting to call .perl on all
of the attributes

The RT System itself - Status changed from 'new' to 'open'

Now generates something that is probably reasonable​:

Closable with tests.

From @usev6

skids++ added a (passing) test to S06-advanced/callframe.t with commit Raku/roast@92b416ca8b

I'm closing this ticket now.

@usev6 - Status changed from 'open' to 'resolved'
