Tribbles are real, and they can control a homunculus reasonably well. 
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

The whole thought of processing the exception first upon returning from a call is so counter intuitive to the way we think; we process good/expected results first, THEN proceed to look at the outliers.
When I read the code, I think the developer is expecting an error so prepares to handle it first.
It all goes back to the maxim: write clean code; there is nothing wrong with indentation or else statements. Also, write comments on what the process is doing and why, don't assume the code is so well written its intuitively obvious what the desired result is.

Agree with the why. I can read the code to see what it's doing. I've seen so many comments // declare variables then // call the function then // process result
So helpful.
Tim Carmichael wrote: there is nothing wrong with indentation or else statements
egregious indentation and if/else's are problems when there are too many levels, usually more than two. This leads to functions that are too long and have multiple purposes. Better to refactor the code and move the different cases into different functions.

I absolutely agree with this...
The worst If/Then block I ever had to write was in Fortran for some equipment routing in an automated factory. The 'If' statement was 23 lines - and that is just the 'If' portion, not the code executed if the statement was true.
I had a block of comments preceding it explaining what it was doing and why with a warning that 'if you break it, you get to maintain it'.
But, if was an if/then/else block to determine an action; it wasn't multiple nested blocks within each other.

It's a mixed bag for me. I prefer to exit a method as early as possible, when it makes sense (performing sanity checks on method parameters to ensure they're not null at the top of the method, and throw argument exceptions if they don't meet expected values). After that, I let code go where it needs to go, letting the "true" conditions happen first, and let else handle the "false" conditions.. In the end, I also strive to have a single point of exit instead of having multiple returns sprinkled throughout a method.

That can sometimes produce code that looks like an extortionist got hold of it. Here's were some judicious use of goto may be warranted.

Just say no to goto.
I typically define a result variable, and progress through the method setting that variable as appropriate. If I have a longish chain of if/else clauses I indent them like so:
int result = 0;
if (condition)
{
}
else if (condition)
{
}
... and so on
return result;
If conditions are favorable, I'll use a switch statement instead of if/else, but I still try to have only one exit point (exceptions notwithstanding).
I also strive to keep my methods short and specific to the process/task described by the name of the method.

Yeah, I know. But debugging is exciting enough without adding multiple-exit-points sauce.

My code is always intuitively obvious, since I intuited it, until the next day, that is!
