Because Erlang was designed for systems that are
supposed to be running all the time, even when you
want to install upgraded software with *different*

There have been several attempts to provide type systems
for Erlang.  It took a long time to get one that was
found to be satisfactory in practice, but it's there now
in documentation and in the Dialyzer and Typerl.

However, even that system is not as expressive as one
might wish.

Probably.  Can you give an example of a problem you had
recently where you found yourself digging into the source code?
