--- Comment #3 from Jonathan Wakely  ---
Now we say:

43253.C: In function 'int main()':
43253.C:4:13: error: expected identifier before 'int'
4 | x->~int();
  | ^~~

I suppose we could add a more specific diagnostic saying you can't do this.
It's not a high priority, because the code is nonsense anyway. Why would you
want to destroy an int explicitly? A pseudo-destructor call is only useful in
generic code where you don't know what the type is.

REOPENing as a diagnostic enhancement. I know that the quality of the
diagnostics from the parser is not a top priority but I still hop that someone
may someday improve this a little. And this error could be so much clear...
