Some truly ugly code is like... well, it's so ugly that it either
should be scrapped, rewritten, or propped up so it keeps working.
Hoops?? I'd be willing to build a wall of 'custom interfaces' around
that piece of code to avoid having to touch it! I'd be willing to
burn my RPG debugging templates to avoid having to touch it!
This is -result- of "most software is continually modified." By
people who didn't understand the program, and just patched the 'bad
parts.'
The problem is that if it works correctly, and if it is truly ugly,
it is dangerous to The Company to monkey with it.
That piece of ugly code is likely -filled- with important business
logic! Ideally, the logic should be extracted into a nice,
streamlined, well-designed, well-written, well-documented, easily
maintained module, that can be called from any program that needs to
use that logic. And that's one of those "Major Projects" that's nice
to dream about, but we -really- "need" to add that GUI interface to
the order entry system first...

Imagine the ugliest piece of code you have to work with on a
periodic basis....
How much of a headache is that? How many hoops are you willing to
jump through to avoid having to change that legacy code.
