in thread logical non-short-circuit operators

You're right, of course. The reason I avoided the former approach was because I have a lot of similar statements and I was hoping to keep the assignments in the scope of the conditional so as not to pollute the namespace or by accident reuse an old variable.

    If you have many similar statements, maybe you could refactor them to use a table for the conditions and a loop (or so), or in some other way. Code duplication or near-duplication is usually a sign that you can do it better somehow.

    If you want to avoid the variables leaking out, you can just put another block around the whole thing (variable declarations and if block).
