No error on type argument after constructor name with implicit new

[askeksa-google]

This program gives no error in the analyzer:

class Foo<X> {
  Foo.bar();
}

main() {
  Foo.bar<int>();
}

See also #34159

This also does not produce any errors on the VM, so I believe that it's working as intended. Why did you expect to see an error?

[askeksa-google]

Foo.bar is a named constructor. Named constructors do not take type arguments, but one is supplied here. The correct syntax for supplying a type argument to the class during instantiation would be Foo<int>.bar().

The VM does not report an error because it generally is missing an error for supplying type arguments where they are not expected: #32972

Ah, of course! Too subtle for me after a day of triaging issues. Thanks!
