You mean the string length? But what's the point of using `unsigned int`
if we have shorter and more elegant `u32`, which at the same time
explicitly states its width? :)
I've been encouraging lots o' folks to prefer the "shorties" where
possible (I basically only use {,unsigned} long from the "basic" types)
and now this :p I'm not saying any opinion is correct or incorrect here,
since it's a matter of taste mostly I believe, just curious.
