Test case:

----------------------------------
struct Foo {
    enum __ctor = 4; // can also be a function, struct, alias, but template is
ok.
}
void main() {
    auto f = Foo("irrelevant"); // can also use 'new Foo(...)'
}
----------------------------------
Assertion failed: (td), function semantic, file expression.c, line 7040.
Abort trap
----------------------------------

Names beginning with a double underscore are reserved for the compiler's use.

(In reply to comment #1)
 Names beginning with a double underscore are reserved for the compiler's use.


Should we implement some kind of identifier checks in the front-end? We could
gather all double-underscore symbols the compiler uses and just compare them
when instantiating Identifier from user-code.

Unless the compiler also generates these symbols with random names, in such a
case we would have to ban all double-underscores identifiers in user-code
because they might potentially clash.
