01:11 <simon-az> Hi there, I am not very versed in FP and Lips in general, but I like Racket as an exercice to challenge myself with different ways of thinking and solving problems. (I am a veteran PHP dev - doesn't mean much lol) and I use Racket for tools helping me in my tasks daily.

01:11 <simon-az> I was wondering if I could post some links to my gitlab for people to give me insights on what I am doing right or wrong.

02:12 <shawnw_> Sure. Just don't expect fast (Or any) answers. The discourse site might be better than IRC for stuff like that. Or the discord, but I don't use that so wouldn't really know.

02:13 <simon-az> I see, thank you. I am in no hurry anyway. Here is a link to a file: https://gitlab.com/simonced/devmemo/-/blob/master/racket/image-desktop_generator.rkt?ref_type=heads

02:13 <simon-az> I don't know discourse, I'll go have a look as well.

10:32 <msiism> Is the handler expression in a `with-handlers` form necessarily a lambda? If so, why?

11:15 <bremner> msiism: not sure if this is your question, but any place you can write a lambda you can write an identifier bound to a function (e.g. via define)

11:16 <bremner> afaik it does have to be a procedure. I might have missed something though

11:20 <msiism> Okay, tested it. It does have to be “a procedure that can be applied to arguments.”

11:21 <bremner> it's weird to me that it is not more precisely documented in the reference manual

11:22 <msiism> I have a bit of a hard time understanding the structure of `with-handlers`.

11:23 <msiism> I'm looking at the first example in https://download.racket-lang.org/releases/8.18/doc/guide/exns.html and asking myself two questions:

11:24 <msiism> Well, one, actually: Why does the lambda have an `exn` parameter if it's not used in its body?

11:32 <msiism> Apparently, that is because the handler procedure takes an argument of struct type `exn` in order to potentially use some of that struct's contents.

11:37 <msiism> It just doesn't do that in the given example.
