#! After continuation is being captured, the stacks looks
#! like:
#! ( f continuation r:capture r:restore )
#! so the 'capture' branch is taken.
#!
#! Note that the continuation itself is not captured as part
#! of the datastack.
#!
#! BUT...
#!
#! After the continuation is resumed, (continue-with) pushes
#! the given value together with f,
#! so now, the stacks looks like:
#! ( value f r:capture r:restore )
#! Execution begins right after the call to 'continuation'.
#! The 'restore' branch is taken.
