For is Go's while loop

Looks like you use for do := true; do; do = condition {}.

You can simplify this to for condition {}

I want to check the condition after each iteration. I couldn't find a more idiomatic way to accomplish that.

Ah, I meant to say you could do:

Rand(buf)
for cond { 
    Rand(buf)
}

Feels a little more obvious about what the loop is doing.

Why not do something like what math/rand does:

seems like the loop you described is exactly what math.Rand does, I'll refactor next time I have a little bit of time. Thanks.
