these need use cases that go beyond what 'with' can do.

If multiple execution of the thunk is allowed and control over break, one usage
would be:

loop:
 <block> # can contain break/continue

instead of:

while 1:
  <block>


Another, if in a program one uses often the if some_cond, e.g.

if ctl.mode == INTERACTIVE:
  <block>

if ctl.mode != INTERACTIVE:
  <block>

one could define:

interactive:
 <block>

notinteractive:
  <block>
