You missed my point, which is to convert SimdSignal to have an API like SIMT's
from a game programmer perspective, we sent dozens of messages over what
exactly I meant in #713.

This is basically the bug for the future improvements that you and David
convinced me to put off for later in the virtual coffee meeting yesterday.
David explained that you thought those improvements were a good idea, so I'm
reopening this bug.
