masak it does have infix ops. 06:11

Ven 007 parses infixes with `<expr> + % <infixish>` ? 12:52
but that's the definition of an expr, isn't it?
masak this method parses infixes: github.com/masak/007/blob/03dd6f8b...er.pm#L191 13:39
I feel like maybe one of us is confused. :)
Ven I am :D 14:27
I want to parse, say "a + b", but if I write `token expr { <expr> <op> <expr> }`, this'll not work well :) 14:28
sorry for the late answer, I'm doing some objective-c, and it's a terrible language 14:29
masak yes, that indeed won't work. 15:03
it's called something like "left-recursive". it loops forever, just like `sub foo { foo(); ... }` would. 15:04
Ven yeah 15:36
that much I know :)
masak I'm sorry, I don't know if there's a topic left after that. :) 15:46

vendethiel right, right. 17:27
but I don't want to, say, look "up to an operator" and parse everything between my current position and that
mh 17:29
I was asking to do a technical review for a book (on coffeescript) 17:30
but I'm afraid I won't find that for that between school and al
masak you were asked? 18:51
yeah, any kind of task like that takes time. usually more than expected. 18:52
vendethiel I received an email, offering me to review one
masak I downloaded and used Coq for the first time yesterday. impressed.
I also read through an entire tutorial on it.
vendethiel never tried Coq! 18:53
I should
masak I especially like how they nicely braid three sublanguages: one for high-level definitions, one for types, and one for proof tactics. 18:54
in that same vein, I liked reading bentnib.org/posts/2015-04-17-propos...-make.html 18:56
somehow that really clicked for me. maybe I'm in an intuitionistic type theory mood right now. 18:57
vendethiel that's a ... very specific mood
masak :D 18:59
vendethiel I'm a pretty bad mood myself, but I can impute that to objective-c/ios programming and sleep deprivation :) 19:00
that was an interesting read 19:01
I'm not much in the type theory field these days
I've been spending some time reading the c++ standard
masak what's your general impression of C++ ? 19:02
vendethiel it's actually very perl6-like, in *some* sense.
"they wondered if that was possible, and never asked themselves if they should do it instead" 19:03
I totally butchered that quote (jurassic park quote?) but that's the sentiment
masak yeah, that's my impression, too
it's the same premise but quite a different result, though
vendethiel right.
as I talked earlier, the fact they implemented lambda in the language before it was added
the fact they have a compile-time-generation of parser (boost.spirit) 19:04
or the fact they created something akin our Whatever (Boost.phoenix)
the fact they have a compile-time regex-compiling engine
the fact they have ....
I guess I'm really interested in learning "deep dark magic" stuff 19:05
and that's why I'm learning this stuff 19:06
I'll never say c++ is a good language
masak *nod* 19:10
vendethiel but it's interesting
as a grew-up-with-backwards-compat 19:11
much in the same way as perl, imho
masak yeah. 19:23
and AngularJS
(been teaching that today)
the directive API... is quite powerful but leaves much to be desired in terms of beauty. 19:24
vendethiel right 19:25
it has this java feeling :P 19:26
masak no, it has this inconsistent ball of mud feeling :) 19:42
