[Feature Request] Add support for LinqPad's `DumpContainer`

[CodesInChaos]

Linqpad supports DumpContainer, which allows updating dumped data in the output window. Adding support for this would be convient for things like progress indicators.

For example:

var dump = new DumpContainer().Dump();
for(var i = 0; i <= 100; i++)
{
    dump.Value = i;
    Thread.Sleep(100);
}

Would output a single number which slowly goes from 0 to 100.

Yeah, that is useful. I'll see what I can do.

[CodesInChaos]

For now I'm using expiring dumps as workaround:

void ProgressIndicator<T>(Func<T> getValue, int milliseconds)
{
    var timer = new Timer(_ =>
    {
        var value = getValue();
        value.Dump(clear: milliseconds);
    }, null, 0, milliseconds);
}

Though that comes with some thread safety issues, and possibly makes the progress jump around in the output.
