04:19 <abrown> I'm struggling with class inheritance in RPython; in talking to cfbolz earlier I realized I needed to switch over to _immutable_fields_ from _immutable_ because in some cases I have a single mutable field. However, when I do so I have to start using _attrs_ but when I do this I get NoSuchAttrError.

04:20 <abrown> Can anyone take a look? Pastebin of error: https://pastebin.com/AhjQC9dc

04:36 <ast-ral> test

04:36 <ast-ral> hello

04:36 <ast-ral> is there any way to check if a program passes rtyping before trying to translate or do you just have to go for it

04:37 <simpson> Just go for it. The second thing that the translator does is rtyping. (The first thing is importing your entrypoint and doing some platform checks.)

04:38 <ast-ral> ok thanks :)

04:38 <simpson> As you get more practice, you'll get more used to knowing what the types should be, and you'll have less trouble.

05:31 <ast-ral> is there a way to do something similar to if type(obj) == SomeType:

05:32 <simpson> isinstance(), usually for subclassing.

05:32 <ast-ral> oh, duh

13:35 <arigato> there's an assert in one path leading to the line, but not the other (when you close the loop)

17:58 speeder39_ has quit [Quit: Connection closed for inactivity]

18:08 <arigato> I think by now that it's something like: the optimized loop is called after a preamble that forces two input arguments to be equal; we correctly don't assume that they are equal in the loop, except in one case: the loop checks that one of them is equal zero, and then replaces the other one with the constant zero too

18:15 <arigato> or some slightly more subtle version of it---at the end of the preamble we have "h == height - 1", the loop checks that "h == 0", and then incorrectly assumes "height == 1"
