What's your favorite C++0x feature? [closed]

Answer 1

Lambdas and Concepts

Answer 2

Lambdas and initializer lists.

Also, the changes to make it easier to eventually bring C++ into a garbage collected model, those seem pretty interesting. Perhaps C++1x will actually bring in garbage collection, but 0x/10 just set things up for the eventuality.

Answer 3

Raw string literals! I thought that python-like string blocks were awesome, but I was wrong! In C++0x raw string literals are incredibly useful for text formatting. Markup languages can be wrote directly in your source!

Answer 4

auto keyword for variable type inferencing

Answer 5

for the moment I have liked much of C++0x that I have played with:

• nullptr
• static_assert
• lambdas
• shared_ptr and weak_ptr
• unique_ptr
• decltype and auto

I havent tried <regexp>... I thought it was a huge idea... but I didn't even take the time to look at it.

Answer 6

I want Rvalues references.

All the other new features are stuff that we could easily live without(alas features). However the lack of Rvalues in C++ so far has caused hundreds of template library authors to have to "hack" around the broken Rvalue ref issue.
