But isn't there the ability to analyze for correctness the following
non-functional requirements. I mean real parallel problems.

boundedness, deadlock, safeness and liveness

It seems to me that one can use a PetriNet analyze the state space for
correctness. Yet, the state space grows incredibly fast. The PIPE tool
is a tool that does just that.

Erlang has low thread creation overhead and immutability of variables,
so it appears that it is easier to analyze. It seems Erlang uses 
messages, has low thread creation overhead, and variables are immutable,
a model to analyze.

make it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies."
