Said one (of three) people who designed OTP in the first place.

Now we are talking! Martin came into my office and gave me the evil
eye btw. :-)

I just say this:

1) Did we have any choice but to use OTP having the three designers
    behind OTP itself in the project? Not.
2) Only a handful of people seems to be able to grasp all what OTP has
    to offer. Klacke and me doesn't after all these years it seems. I
    may just be plain stupid but I know Klacke isn't.
3) There was no alternative at the time. If the thing I describe here
    was in place I would have voted on using that instead.
4) I have worked for years with OTP now and I'm obviously not
    satisfied. That may not mean anything to you. It means something
    for me though.

OK, next *new* project. I don't plan on rewriting all OTP stuff we
have now which actually works.

We should probably not burden the erlang-questions lists with further
discussions about this.

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.
