Idea

The Metavariable-Agda type represents metavariables in Agda.

Definition

postulate
  Metavariable-Agda : UU lzero

{-# BUILTIN AGDAMETA Metavariable-Agda #-}

primitive
  primMetaEquality :
    Metavariable-Agda → Metavariable-Agda → bool
  primMetaLess :
    Metavariable-Agda → Metavariable-Agda → bool
  primShowMeta :
    Metavariable-Agda → String
  primMetaToNat :
    Metavariable-Agda → ℕ
  primMetaToNatInjective :
    (a b : Metavariable-Agda) → primMetaToNat a ＝ primMetaToNat b → a ＝ b
