But every number in TestStand is a floating point number, which means we need to know how to represent it (number of digits past decimal point, etc) and that can't be done well without specifying a formatting string, and I'd be scared to just leave it all up to "%g".
Besides that, there's some good value to type verification for making sure you didn't screw up your expression, and this is moving away from that.
Declining due to lack of community support for this idea.
