{.booldefine.} are not considered constants in type sections

[mratsim]

Test case:

const True {.booldefine.} = true

type
  Foo = object
    a: int
    when True:
      b: int

Error:
Error: constant expression expected

Workaround with static so tagging low priority.

const True {.booldefine.} = true

type
  Foo = object
    a: int
    when static(True):
      b: int

wondering if same root cause as #12929

EDIT: no because issue still there despite #12880 being fixed

Maybe this should be backported?
