Walter, just wondered whether we can have VLAs (via alloca()) for
fundamental types?

In other words, rather than having to write something like

    bool  lookup(int id, char *buff, inout uint cchBuff);

    uint cchBuff;
    if(lookup(<someid>, null, cchBuff))
    {
        char[]    buff = new char[cchBuff];

        lookup(<someid>, buff, cchBuff);
    }

it'd be nice to have the option of writing

    uint cchBuff;
    if(lookup(<someid>, null, cchBuff))
    {
        char    buff[cchBuff]; // <== This is allocated via alloca()

        lookup(<someid>, buff, cchBuff);
    }

Thoughts?
