The more we train modern developers that they are, the bigger the problem we will have. Microsoft suggest moving to 64 bits to solve the problem! I suppose I am being a little pedantic. Submit a new text post. On my machine sizeof std:: I think that new programming styles and new languages will start to overcome that barrier with time and experience.

With prefix dereference you need to remember which operator associates more strongly:. Become a Redditor and subscribe to one of thousands of communities. You can’t make abstraction both costless and correct. I found that really weird.

The point is resources are not infinite and they are not ‘free’. Capturing variables – either by value or by reference – is absolutely equivalent to passing them to the constructor of a function object and making them accessible to operator as member variables.


Show only CppCon links. In this respect, function objects are still a better choice. The garbage collection is its achilles heel frankly.

We already have desktop and laptop PCs with multiple cores today, and mobile devices and even embedded systems are starting to go that way as well. Want to add to the discussion?

It disqualifies ‘d’ for some very basic but very important applications. The state of the lambda object has changed between calls. Hardly anyone programs raw assembly today, because getting good performance out of modern chips is a specialist skill and we have compiler writers who spend a lot of time getting joshttis at it, so most of us will josuttiw faster software by writing in those compiled languages and leaving the tricky assembly-level work to the experts.

No, you will never find a performant programming language without joduttis corner cases and programmer traps. Submit a new link. It’s not going to gain popularity by making incompatible changes, and I’ll take backwards compatibility and slight inconveniences over program-breaking changes to the standard for aesthetic purposes.

The new stuff does josurtis a lot of functionality, and that stuff is often damn useful, but sometimes you just want a function pointer. It’s very difficult to scale ‘c’, it doesn’t easily support coding at a higher level. The current trend of sweeping aside all concerns of performance and particularly memory usage produces such ‘gems’ as Visual Studio As commodity hardware gets faster, the commercial pressures push development toward rapid prototyping and product evolution, with less emphasis on achieving optimal speed when anything within a factor of 2—3x or much more, josuttus on the context is still fast enough for paying customers.


In my experience, writing toy examples to understand how something works and solving real problems using it are two very, very different things. With prefix dereference you need to remember which operator associates more strongly: You’re right that this is a deficiency.


Check on this demo on ideone. I thought it was usually the caret, but that still leaves this case ambiguous with bitwise XOR.

That is an extremely difficult theoretical problem and an active research area today, but then a few years ago we might have said something similar about just-in-time compilation, and a few years before that we talked about dropping out of C to write the performance-sensitive parts of our code in assembly language. There are several factors that I think will push the industry in that direction. I think he might have been drunk. That one application josutits consumes over 2GB of memory when you load a project.
