Well, this is what I think I'll put into production, unless anyone can show
me any flaws in it. It seems to work fine as a float in my rudimentary
tests.

namespace jml
{
    class Float
    {
    public:
        Float( float Value = 0.0f ): Value( Value ) {}
        operator float() { return Value; }
        float Value;
    };

    std::istream& operator>>( std::istream& is, Float& mf )
    {
        if ( is >> mf.Value )
        {
            if ( mf.Value == 1.0f && is.peek() == '#' )
            {
                std::string Rest;
                is >> Rest;
                if ( Rest == "#INF" )
                    mf.Value = std::numeric_limits<float>::infinity();
            }
        }

        return is;
    }

};

I'll probably make Value private just because.
