DMD metaprogramming enhancement

[Suleyman via Digitalmars-d-announce]

Hello everyone,

I am happy to announce that in the next DMD release you will be 
able to more freely enjoy your metaprograming experience now that 
a long-standing limitation has been lifted.

You can now instantiate local and member templates with local 
symbols.

Example:
---
struct S
{
    private int _m;
    void exec(alias fun)()
    {
        fun(_m);
    }
}

unittest
{
    int localVar;

    void set(int i)
    {
        localVar = i;
    }

    auto obj = S(10);
    obj.exec!set();   // no error or warning

    assert(localVar == 10);
}
---

I hope you enjoy!
