Bug: prepared statement parameter is not produced for any class or object, "incompatible interpolation" is not thrown

[Awethon]

In case when specific enum entry subtype is used instead of general one, doobie constructs a query without any errors but prepared statement parameter is missing.

Code:

sql"""
  SELECT col1, col2, col3
  FROM table_name
  WHERE state = ${MyBoolean.True}
"""

Expected:

SELECT col1, col2, col3
FROM table_name
WHERE state = ?

Actual:

SELECT col1, col2, col3
FROM table_name
WHERE state =

Usually when there's no implicit doobie fails, but for some reason this is not the case for enumeratum.
Seems to work correctly (throws error) in 0.13.4 but doesn't work in 1.0.0-RC5.

UPD: Seems like this issue is not enumeratum specific. It doesn't fail for any class or object in sql interpolation.

I guess this is because ${MyBoolean.True} is observed as MyBoolean.True type, not just MyBoolean.
For example, this change seems fixing the issue:

sql""" SELECT col1, col2, col3
       FROM table_name
       WHERE state = ${MyBoolean.True: MyBoolean}
  """

But I agree that it can be very confusing.
