It's certainly good to have less lines of code to write and
to debug. And to be able to use the time that would be
otherwise required for those lines of code to do something else,
like more intensive testing, or adding a feature.
Or in another words:
Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are, by
definition, not smart enough to debug it.
(forgot who said it)
Well, true to some extent.
The argument though is this:
If you write a "good code", you won't have to debug it as much.
If your design is "correct", then you don't have to debug it much.
And again, remember what Denis Ritchie said about logging
(not a literal quote)
People get lost in the local scope with debuggers and can not
see the forest from the trees. They keep looking at the values
of local variables and small things like that and end up spending
10 times more time on debugging.
Instead, he proposed to use a well designed logging system.
That way, you can identify problems with your code probably
10 times as fast as with debuggers.
What an insight!
