"1 or false and true or false" should be interpreted as "(1 or false)
and (true or false)", which should evaluate to "(1) and (true)", which
should evaluate to "true", not "1" ("The conjunction operator *and*
returns its first argument if this value is *false* or *nil*;
otherwise, *and* returns its second argument" - Lua manual).
