Compiler fails to synthesize ValueOf for singleton this.type

[rcano]

Compiler version

3.6.x, 3.7.0-RC4

Minimized code

class Test { summon[ValueOf[this.type]] }

Output

-- [E172] Type Error: ----------------------------------------------------------
1 |class Test { summon[ValueOf[this.type]] }
  |                                       ^
  |No singleton value available for (Test.this : Test); eligible singleton types for `ValueOf` synthesis include literals and stable paths.
1 error found

Expectation

This a singleton type with a singleton value that can only ever be created in exactly one way. The compiler should be able to synthesize this like it does for any other singleton value
