True.  But isn't this an awfully weak proposal?  It doesn't seem to allow me
to cleanly compute additional state that's used only in assertion checking.
I find that I need to do that all the time in order to be able to write
reasonable assertions.  For example, I might explicitly keep track of who
holds a particular lock, so that I can assert that I hold it at some point.
Or I might need to count opened files so that I can assert that I closed
everything I opened in a certain section of code.  Or ...
