That's the debugger friendly version, as you can set a breakpoint on the
error case.
This one is equivalent, but you can't break on the error case:
foo = bar();
return foo;
This one is the least friendly, since you can't break and view the
return code at all:
return bar();
I usually code for clarity and ease of debug, and I leave it to the
compiler to optimize far better than I ever could.
