nogc v0.5.0 - DIP1008 works!

[Atila Neves via Digitalmars-d-announce]

I'd been holding off on announcing this until DIP1008 actually 
got implemented, and now it has:

https://code.dlang.org/packages/nogc
This dub package has a @nogc version of `std.conv.text` (which 
probably isn't as good yet) that, instead of returning a `string` 
returns an `automem.vector.Vector` of char. This handles managing 
memory allocation for the exception message itself in 
`NoGcException`, which does what it says on the tin. Confused? 
Here's some code:


@safe @nogc unittest {
    import nogc;
    import std.algorithm: equal;

    int a = 1, b = 2;
    try
        enforce(a == b, a, " was not equal to ", b);
    catch(NoGcException e) {
        assert(equal(e.msg, "1 was not equal to 2"));
    }

    try
        throw new NoGcException(42, " foobar ", 33.3);
    catch(NoGcException e) {
        assert(equal(e.msg, "42 foobar 33.300000"));
        assert(e.file == __FILE__);
        assert(e.line == __LINE__ - 4);
    }
}

It doesn't leak memory either, as proved by ldc's asan.
