It doesn't eliminate the [t b f], it makes them more manageable.

it's just a bunch of [inlets] connected to a [pack 0 0 0 0 0] then to an 
[unpack 0 0 0 0 0]. This causes recomputation of the complete tree of 
maths every time something is sent to the hot inlet of the abstraction, 
but it doesn't fix anything arising from crossing wires in ways that would 
usually cause a delay: for example if you use [t f f] with crossed wires 
to an object, instead of using [swap], this causes a delay (intentional or 
not) due to order of operations.
