I've been coding C++ since '98, and coded a lot of toy languages (like Onyx) for hobby, and it's always killed me that not all flow control constructs are expressions.
1:12:30 They do not have the same captures. The second lambda captures the first as well as steps. If they both said [&steps] instead of [&] then they'd have the same captures.
@@erichopper4979 ; What? Why would you expect it to capture reference for things that aren't even used? You would have to make a reference for a LOT of things.
There really needs to be some rules about when a person can interrupt a talk with questions. This is ridiculous. I can't even watch this. Great talk though! Wish people would STFU.
Part of the point of CppNow is the collegial nature of the talks. I have heard speakers (really smart ones) say that they give talks at CppNow so that they can learn from the audience (many of whom are also speakers at the conference).
1:18:14 - I've written the beginnings of something that does this. I haven't really finished it to the point that you can write expressions like that, but that's mostly because it seemed like it would turn out to be really slow, Though I didn't thoroughly test it. It's the Sparkles library bitbucket.org/Omnifarious/Sparkles - I do *not* want this fancy stuff he wants involving operators. No! Make a new language if you want that.
A warning for future viewers: there's an attendee who seems to be about to cough up a lung. It's quite distracting. I hope they got some relief and didn't infect the rest of the folks.
I was sitting in front of the poor fellow. There was a good portion of the room having issues with allergies and congestion. The mountain air was kinder to some more than others.
Ben's talks are always informative.
The class at 47:49 allows some neat code. However, I want to know about the compile time impact.

1:30:54 Question: How do you identify monoids in your code? Answer: Ben's 2019 excellent talk: th-cam.com/video/INnattuluiM/w-d-xo.html
Nice talk indeed!
I am looking for slides in the provided links, but the page says that no slides are available... how misleading.

does any1 know what color scheme he uses?
very nice talk, thank you
Glad you liked it!

No, [&] means that all *used* variables will be captured by reference. The second lambda doesn't use the first one so it doesn't capture it.
orbital1337 - oh. Interesting, I didn't realize that. I don't like that. You need to understand too much context then to know what [&] means.

@AODQ - That is how a simple '&' capture is defined.
@@erichopper4979 2 years later, but. What would be the point of capturing variables not used? You gain nothing from it.
