All of
comp_ctx_assoc
comp_ctx_inj_r
comp_ctx_emp_r
arise only in the proof of
step_same_ctx K K' e e' :
fill K e = fill K' e' ->
reducible e ->
reducible e' ->
K = K'.
Moreover, comp_ctx_positivity gets used only in step_same_ctx
and
atomic_fill e K :
atomic (fill K e) ->
~ is_value e ->
K = empty_ctx.
It might be simpler to (prove and) assume these two rather
than those four.
