Of what use is 'lambda'???

It would be possible, if you can read the state from the telco switch,
instead of keeping a model of your switch in memory. If the language
really forces you to do that, then you need to think deeper about the
hardware. In this case you need to build a switch with an input (for switching)
and an output (to report its state back to the program).

Regards,

Jurgen

They must be some non-functional parts of the language.  If
none of the functions have side-effects, then there's no way to
change the state of a telco switch for example.  A telco switch
that can't change state isn't too useful.
