I feel like I haven’t quite figured out the right tricks for using the boolean expression operators (`Expression&lt;Boolean&gt;.and` and friends) w.r.t. operator precedence. Do I just need to always parenthesize every sub-expression? I guess Kotlin doesn’t really do precedence levels of custom infix operators?

In the case of `columnA eq true and columnB eq false` I believe that `and` and `eq` have the same precedence because they are both method calls, so the compilter thinks you are trying to execute `(columnA eq true and columnB) eq false` which is obviously not correct.

The style presented int he docs is to use `columnA eq true and (columnB eq false)` meaning you should parenthesize everything but the first statement, but it can't hurt to also parenthesize the first statement if that looks good to you.

i guess infix ops are left associative which is why you don’t need the first one?

yeah i’ve been doing that. intellij indentation for it isn’t beautiful though
