New/Changed Features

• Added std.string.soundex.
• Added std.string.entab.
• Added std.string.wrap.
• Added std.string.abbrev.

• Added std.demangle to demangle D names.
• Improved promotion of names inside templates.
• Now allows floating point and string literals as template value arguments.
• To support the previous, the name mangling of template instances has changed. This will necessitate recompilation of any code that uses templates.

比较感兴趣的是浮点数和字符串常量作为模板值参数，简单测试了一下：

import std.stdio;

template TFloat ( float  F)
{
     float  value  =  F;
}

template TString ( char [] S)
{
     char [] value  =  S;
}

void  main()
{
    alias TFloat ! ( 3.14f ) PI;
    writefln(PI.value);
    writefln(TString ! ( " hello " ).value);
}

编译通过，运行结果如下：

3.14
hello
