In your specific example, it didn't look like you wanted to use that array, so I thought I could save you a variable. If you are planning to use it, then by all means bind it to a variable for reuse.

What other use is there for a conditional let?

I thought your only use for the array was to check its count. Now that I think about it, that was probably a stupid assumption.
