Big process effort.  The only thing I know of that is worse is DO-178,
the process for development of avionics software that is
safety-critical in the sense that failure leads to loss of airplane
and all aboard.

I hope you are able remain sane.

Yeah.  I'm with the old guys on this.  We paid our debt to process and
was paroled for good behavior decades ago, and don't want to repeat
the experience.

Reminds me of Structured Programming (which forbids Go-To statements):
..<https://en.wikipedia.org/wiki/Structured_programming>

Problem was that the Process Police tried to force me to follow this
in operating-system kernels.  Well, I'd like to see somebody build a
kernel without go-to statements.  

The deeper problem is that structured programming basically requires
that the flow chart can be drawn on a 2D surface without any
cross-overs - the nesting must be perfect.  Well, good luck following
that with real computer hardware, never mind the special hardware that
the computer controlled.

Think parallel Finite State Machines interacting and interweaving at
random, driven by random external events.  Not even a 3D flow diagram
suffices.

So in this case, I didn't even attempt to document according to
Structured Programming, instead telling the Process Police to buzz
off.  I only had to show them a real kernel listing once - a wall of
assembly code.  They had seen only toy examples in textbooks.
