The compiler only warns when it finds obvious discrepancies when trying
to optimize the code. Arithmetic expressions involving a variable cannot
(in general) be optimized, so no warnings are generated.

A future version of the compiler will probably do more type analysis and
will generate more warnings (and optimize the code better based on the
type analysis).
