Uniform Function Call Syntax(UFCS) and @property

[kenji hara]

Additional point in my opinion:
Calling UFCS-able annotated function by normal function call syntax is
still vaild.
But not annotatied function shouldn't be allowed with member-like call syntax.

void f(T)(T this, int n){...}  // UFCS annotated
void g(T)(T x, int n){...}    // do not UFCS annotated

struct Foo{}
Foo foo;
foo.f(10);   // member-like syntax - ok
f(foo, 10);   // normal call syntax - still ok - UNIFIED function call syntax.

//foo.g(10);   // Invalid
g(foo, 10);    // normal call syntax - ok
