Note that I still have on my list of things to do to rework
the 'block of commands' patch that I started some (long) time ago.

One of the objectives was to allow to group commands in blocks such as:

{ command1 ; command2 ; command3 }

And have (optional) flags -c and -s to follow the {
to control continuing (silently or not) the execution
of a sequence of commands when there is a failure.

Another objective is to allow something like:
  thread apply all { command1; command 2}
and similar for frame apply,
