There are features - such as type and property inference - that many would agree are useful, subject to proper language integration. But then there are features of which utility is not immediately obvious, and that could go either way when it comes to community adoption and scaling up to real, large programs. This talk discusses three such features of D - seemingly unimportant, maybe greeted with a ho-hum by the community, but today ubiquitously used and enjoyed. en Sun, 26 May 2013 01:40:28 GMT Sun, 26 May 2013 01:40:28 GMT Rev9 Re: Andrei Alexandrescu: Three Unlikely Successful Features of D posted by chethan

There are many possible fixes, his proposed one being among the simplest.

The idea here is that if the range is left at exactly one element, it can't be reduced from both sides (one size suffices).

bool palindrome(Range)(Range range) {
    for (; !range.empty; range.popFront(), range.empty || range.popBack()) {
        if (range.front != range.back)
            return false;
    }
    return true;
}

I have a question if you think that C++ based ScopeGuard or Boost.ScopeExit with std::uncaught_exception() usage can be the same robust as in D?

Now guess who invented former :)
I'm a little curious why this didn't find a mention at all?

"cannot detect exceptional return"
Usually this is not a problem since there is only a single place where the "task is fully completed", that is where you place the "dismissed". All other code paths, e.g. exception, premature return, do not matter.

> Some first naive implementation
Why not use an elaborate one?
Like Loki's:
http://loki-lib.cvs.sourceforge.net/viewvc/loki-lib/loki/include/loki/ScopeGuard.h?revision=1.6&view=markup

Or an C++11 optimized version:

Always thought you had to be from another planet, you blew it with that move at 11:55!

Keep it up! Really starting to see the point for D, to me it has a bright future. If you can implement pattern matching you will rule the planet with this (after some libs are converted obviously).
Wish I could use it here..

For example:

try
{
    int some_var=1;
    cout << "Case #1: stack unwinding" << endl;
    scope(exit)
    {
        cout << "exit " << some_var << endl;
        ++some_var;
    };
    scope(failure)
    {
        cout << "failure " << some_var  << endl;
        ++some_var;
    };
    scope(success)
    {
        cout << "success " << some_var  << endl;
        ++some_var;
    };
    throw 1;
} catch(int){}
