/* NM_BOOLEAN_EXPR(expr) exists to ensure that there is still a compiler
* warning when accidentally(?) using assignments like `NM_BOOLEAN_EXPR(x = 1)`
* Compiler will warn about that and suggest either == or additional parentheses
* `NM_BOOLEAN_EXPR((x = 1))`.
*
* This also is true for users of this macro, like `NM_LIKELY(x = 1)` and further
* up `nm_assert(x = 1)`. Those users must make sure not themselves adding additional
* parentheses around the condition.
