Below is a self-contained DRL which should not compile because the sum
isn't a boolean expression. (Note that omitting $x: results in the
correct diagnostic predicate ... must be a boolean.)
declare Foo
a: double
b: double
end
rule what
when
$c: Foo( $x: a + b )

Wolfgang,
Thank you for reporting. Mario is fixing it.

should be disallowed from Drools 6 forward? Things like:
Person( $name : name == Bob ||
I guess I've always spoken my mind in favour of a clean syntax, even
if it means a little extra typing. I dislike expressions with internal
bindings; the traditional binding at the start of an expression is
sufficient.
