There is less verbose repeating of verbosity. But the types did not change in anything like the way that I would like.
Try to translate http://perl.plover.com/Stream/stream.html into C++ iterators to see how the current abstraction limits the ways you can think about a program. By contrast suppose that my hypothetical iterator< foo > type was required to have a pointer overload, and supported the methods done() and next(). Now go back and try to translate that article - you'll find that it is pretty easy.
The interface that I describe can be backed by a collection, data streamed externally (eg from a file), or by something generated on the fly. Therefore you can write code for all three cases that looks very similar.
That article demonstrated the power of this idea by writing code that fairly efficiently generates the Hamming sequence, which consists of all positive integers whose only divisors are 2, 3, and 5. (So 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, ...)
You can create your own type of iterator that when dereferenced spits out the next number/item, So long as your "end" iterator never matches your "current" iterator it will continue going on. Your "done" function is when "current" and "end" match. "next()" is "++current".
Indeed. First off, it is unrealistic to expect to rewrite perl/python scripts (much higher level scripting languages) in C++ and expect the same level of succinctness.
C++ is for larger , high performance applications.
The piper needs to be paid one way or another. If you rewrite a perl script in C++ for performance, the relative increase in verbosity is the price you pay.
I accept that a price has to be paid for performance.
However I believe that a substantial amount of verbosity could be removed without impacting said performance. In fact C++11 removes some with type deduction.
I also get tired of typing some_big_type foo = some_big_type(); - is there a way to say, "I want this thing, and I want it to get the obvious default initialization?" Because what I type now is straight from the redundant department of redundancy department. (Yes, a typedef can make that shorter. You still write the idea twice.)
