Why use while if only iterating once ?

There's also the benefit that FLAGS f exists only until the end 
of the loop, and thus won't be polluting the namespace later in 
the function.

Personally, when I want to make a block just for grouping code, I 
use if (true){} or static if (true){} depending on whether I want 
to it's variables go away afterwards.

IIRC, I could just use braces without any header intead of if 
(true){}, but the code block just isn't as easily distinquishable 
without anything at the top IMO.
