your abstraction inversion example doesn't apply here. The problem I
see is the narrowing implicit cast, i.e. int values behave like
booleans. I have no problem with the reverse which is what your

An int does not convert to bool implicitly. An int can be tested with
"if", which is a different thing.

that is an implicit cast.
No. An implicit cast is this:
int a;
bool b = a; // doesn't compile
or this:
void fun(bool);
fun(5); // doesn't compile
You are mistakenly presupposing that if() takes a bool. In reality if()
accepts a bool, an integral, a floating-point type, a pointer, an array,
or a class reference.
