UFCS can be used to emulate adding new members/instance methods to a

class Foo

void bar (Foo foo, int x) {}

Is it possible, somehow, to emulate adding new _static_ methods to a
class,
something like this:
void fooBar (/*something*/, int x) {}
Making this possible:
Foo.fooBar(4);

I'd expect it to look like this:
void fooBar(Foo)(int x) {}
That looks too much like a template function to me. What about:
void fooBar(static Foo, int x) {}
static?
Oh boy, here we go again ... ;)
Note: no parameter name for the "static" Foo parameter (as it's not
really a parameter - simply a placeholder to indicate it's UFCS).
C# doesn't have static UFCS (called "extension methods" in C# parlance)
tho some people have wanted it:

I guess the reason it doesn't exist is that there is no technical reason
for it, all it gives you is a nicer syntax.
You can get fairly close with a custom static class, static method
taking an instance of the class you want to 'extend'.
