I think you have hit on something rally important there. What really
distinguishes a decent programmer from a standard corporate developer
is the ability to understand code rather than hacking something
together until it appears to work.

In my area of security, I'm constantly going round in circles
rejecting patches which can be defeated with only slightly changes to
attack code, or they blame the attacker (like selling faulty fire
extinguishers because you shouldn't have fires), or whatever. Often
it's really difficult to determine whether the bodge they've made
completely fixes the bug. On the other hand, a good programmer can
come back with a fix to a relatively difficult problem in minutes.
