I contend that   x )= f   captures some perfume of the invariant you mention, 
although I admit there is no comparably simple formula for the relaxed invariant 
(if indeed it exists).

Note that current python syntax requires any ) to follow a ( that it balances,
so that's not one but two rules broken in coordination.
