On the newsgroup KennyTM~ pointed out that opDot() also suffers from this
problem:
struct S {
int s;
}
class X {
S opDot() { S temp; temp.s = 6; return temp;

It's easy for the compiler to know that s2.foo.x = 5 does nothing. When
compiling with noop, the void x(int n) { _global = n;}

Of course, s2.foo().x(5) violates the principle at play here. At this
point,

This assumes that the body of x is available for analysis and is simple
enough to be analysed.

You make it sound like we wouldn't be able to use structs anymore!
Not the case.

OK then that's another (potentially worse) problem because I can think of
several cases where I want to return a struct (by value)

That'd be a start.
The problem then is that variable assignment is equivalent to function calls
with 1 parameter due to the

See above. Without analyzing the function bodies, Applying all this to
functions will also ban things I'm not willing to give up.
