I've rechecked the llvm style guide. It doesn't say anything about<br>
this particular issue, but this syntax is used throughout the examples<br>
demonstrating other things.<br>
<br>
What I like about this syntax is that it makes it clear that the<br>
variable has no meaning outside of the if block, which is the same<br>
reason we declare variables inside the for() statement. But those are<br>
microscopic details I'd leave to the discretion of whoever is writing<br>
the code.<br>
