Supervisor trees.

More and less complex restart strategies.
Possible to nest supervisor in supervisor trees to group gen_servers having
this or that common crash recovery pattern. Hot code swapping, which we
never use in the field anyway etc = To much generic robustness library

All this to make it possible to build really large, soft real time, robust
systems. This used to be the charcteristics for Telecom projects. This may
have become relevant for *all* software projects out there today. It's just
a pity that so few has understood this (at least if we compare the Erlang's
user base with for example Python's.).

I believe it would be easier to gain more Erlang followers if we had a
simpler middle way to achieve what OTP promises, i.e. the thing I propose.
If you think the user base is unimportant or me being silly and rhetoric
you are probably right.

If you think the pen is mightier than the sword, the next time someone
pulls out a sword I'd like to see you get up there with your Bic.
