I can assure you I did.
MOSTLy in assembler. The project managers job was to carve it out into
small chunkes that a single coder COULD handle and write the interface
specs so that the assignment of blame was self evident, and to enforce
coding standards sos that the next person along COULD understand waht
had been written. Keep it simple, don't be clever, comment clearly.
EVERY functional block HAD, on pain of being fired, to say what global
variables it used. So you could grep through the code to fouind out
which functions did that.
Every functional block HAD to explain in English, what it was supposed
to do, and comments throughout the code related to these comment block
to show which bits of the code were supposed to actually do what was
listed above.
I may these days hack with less comments, but if my code does NOT work I
go back to that style of comment. At least it reminds me weeks later
what the code is SUPPOSED to do, even if it doesn't.
I've found aids good for syntax bugs, but not for logical bugs.
A proper compiler and proper language that requires explicit
declarations of variables takes care of most of the syntax.
The logic? that you have to figure out the hard way.
But at least if the comment sasy 'check dumledore has been initialised
by Hogwarts' and the code says otherwise, you have a hint...
The trouble is PHP allows lazy coding. Type $dumbledore and its not
clear whether the variable is being assigned, set, or both. Slack typing
means that you need === as well as == and = ...
It truly is a hackers language.

Ineptocracy
(in-ep-toc’-ra-cy) – a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.
