#2In python, lambda usage extremly beautiful. Also, 'lambda' keyword solves readibility problem.
I expected a keyword. Is there any challenge to add keyword?

Backwards compatability. Old valid code should remain valid. That includes code which calculates wavelengths.

Not shown in this article are all the things you can do within the [] (typically just [&] or [=]), which turns a simple lambda into a closure.
The syntax is a bit arcane, but it does what it needs to. They could've stuck a "lambda" keyword in front of it all, but it's not necessary, and making a new keyword always has the potential to break old code.

#5As someone currently learning C++ the biggest surprise was finding out about C++11/14. I'd assumed that the language hadn't changed for decades so it's great to see it still being updated.

An interesting example of C++ not being able to introduce new keywords is the co-opting of auto in C++11 from a storage class to type deduction.

But they had a decent justification: the auto keyword literally did nothing in C++. The only place it was valid, it was also the default.

I don't like that in python you are enforced to only use a single expression in lambda. Sure, writing long lambda functions is ugly but I don't think python should enforce a given coding style in the language level.

Yes. C++ is in an active standard update process. Here is a short history of notable versions:
Year Version Year-Delta
1983; 1.0; 0
1989; 2.0; +6 years
1998; C++98; +9 years (first ISO standard)
2003; C++03; +5 years (minor update)
2011; C++11; +8 years (major update)
2014; C++14; +3 years (minor update)
The C++14 version was the first that arrived on schedule. The next major version is planned for 2017. The future looks quite promising for C++.
