This feels a bit of an overkill for what I am suggesting - after all it is
a single template header file (that does not require precompiling).

I do not see how what I have will affect the exception handling in any way,
but I will add tests for this too.

What I am suggesting is a very simple system to help for resolving the
mentioned in the introduction issues. When a global object receives the
control to initialize itself, it could apply whatever conditions and
whatever source of input. It looks like the DAG system you are referring
have a completely different scope of tasks that it was/is solving.

I have feeling that we are talking for two completely different things. I
have a very raw version of the GOM here: https://github.com/ggeorgiev/gom.
If you would like to keep referencing your DAG system it will be helpful if
you provide a little bit more information about it. Do you have it
published somewhere?
