Great! Keep up good work!

One note thought: I see that there are some new features borrowed from 2.057 log. Is this on purpose or an oversight?

I don't know. See: https://github.com/D-Programming-Language/dmd/pull/582

The following no longer works and is not listed in the changelog:

----
void foo(T...)(T)
{
}

void main()
{
    foo((string, string a){
        // Do something
    });
}
----
It now gives:
----
test.d(1): Error: cannot have parameter of type void
test.d(1): Error: variable test.foo!(void).foo._param_0 voids have no value
test.d(7): Error: template instance test.foo!(void) error instantiating
test.d(7): Error: template test.foo(T...) cannot deduce template function from argument types !()(void)
----

I assume that this is intentional from my following of dmd commits, the breaking change should be listed though.

More @Andrei Does anyone keep an updated version of "The D Programming Language" as changes are made?  I don't know what your publishing agreement was like but could you keep the text of the book in say github.

Is UFCS DOA? Here is my experiment:

struct S
{}

@property int foo(S)
{
    return 42;
}

void main()
{
    auto s = S();
    s.foo();       // Error: no property 'foo' for type 'S'
}

Apparently the only thing that is implemented is that float literals now require [0-9] after the decimal point. That means 1.f and 1.Li will be tokenized as [1][.][f] and [1][.][Li].

Then it sounds like the changelog is in error (though the floating point literal thing is a very good change in its own right).

The member function call syntax that arrays have is a version of this but isn't general/universal, whereas _universal_ function call syntax would apply to all types. So, stuff like 1.abs() and 5.max(3) become legal. It also means that you can declare functions which take a class or struct as their first parameter and call them as if they were member functions of that class/struct.

float x = 1.f;  // GIVES ERROR

float y = 0.f;  // OK

what's up with that?  Is that a bug?

Awesome! And dat changelog! Fantastic work!

I get the feeling with this release D is taking a new direction?! I like it! This is also one of the few D2 releases where my modest pile of existing code just continues to work. Like, I don't know what to do now, just continue to code? like nothing happened?! Teh humanity! :)

Labambda!
thanks
