equalTo not working with the compile-time smart types

[gurghet]

Scala 3.1.2 ZIO 2.0.0-RC6

object Five extends Newtype[Int]:
  override inline def assertion = equalTo(5)
Five(5)

results in

-- Error: ----------------------------------------------------------------------
1 |Five(5)
  |^^^^^^^
  | Assertion Failed 
  |
  |We were unable to read your assertion at compile-time.

  |You must either define your assertion directly or refer to other inline definitions:
  |
  |    override inline def assertion = greaterThan(10) && lessThan(100).

  |    or
  |
  |    inline def extracted = greaterThan(10) && lessThan(100).
  |    override inline def assertion = extracted.

while

object Five extends Newtype[Int]:
  override inline def assertion = between(5,5)
Five(5)

compiles correctly.
