Except the axiom is rather far from the truth, only an ideal.

C++ is more strongly typed than C. I am not a language theorist, but I
believe it is still not considered "strongly typed".

The ability to silently convert from int to char (your compiler might
actually complain about it in some circumstances: a compiler is allowed
to complain about whatever the hell it wants, but there's no requirement
to here, and in most cases, it won't) illustrates one exception,

The reality, though, isn't far from what you state: "all that matters is
that the Standard is the reason". If the Standard dictates you must
issue a diagnostic when such-and-such is attempted, by golly, you will
(except that historically, GCC has ignored this when they "don't feel
like it"; thus the reason for the -pedantic switch).
