Repeat hell, it should shouted from the rooftops.  This is classicly where 
my downfall takes place. I can take a well laid out but buggier than a 10 
day old carcass batch of code and fix it right up, or could in years past, 
just because the original author laid it out well.  But the only from 
scratch item I ever did that was well organized, and just worked at any 
stage of the testing, was one where I'd looked at a screenshot of a 
utility that ran on another platform, wrote up a flow chart based on that, 
and then wrote it section by section, in assembly.  Its a lesson in doing 
the homework, and that utility went together in what I thought was record 
time for a project that was over 20k of binary on an 8 bit machine, and 
without many errors, I think no errors now in its 3rd public release for 
os9/nitros9 systems, as I've heard of none in the last 12 years and its 
still in wide use today on that 'retro' platform.

This was even true 20 years ago.  Any language of the day soon got 
extensions so it could do any other languages job, so that generally is a 
non-starter for an argument point.
