I was talking about if I was to roll my own, I would start by calling a
function I was writing with the key / default value, and it might have a
try block so any error that threw an exception would cause it to fall
back to the default value.
The OP is obviously obviously thinking of something a bit off standard,
or he would just be using a standard config reader, and not need this.
Maybe the issue is parsing the data from the config line into some
internal format, and wanting to catch bad values, like a line that said
"nfiles = 42balloons" that throws when it is expecting just a number.
