Bug 23592 – [REG2.095] deprecation on calling aliased private imported function without parens

Testcase consists of two files, a.d and b.d. Compilation `dmd -de a.d -c -o-` gives the message since 2.095: ``` a.d(4): Deprecation: Function b.C.template_function!int.template_function of type pure nothrow @nogc @safe void() is not accessible from module a ``` The deprecation message is gone when calling _with_ parens: `c.foo()`. Testcase, file a.d: ``` import b; void foo(C c) { c.foo; // c.foo(); // with parens it works without deprecation :-) } ``` Testcase, file b.d: ``` class C { private void template_function(T)() {} alias foo = template_function!int; } ```
