inductive Lean.Elab.Term.Arg : Type

• stx: Lean.Syntax → Lean.Elab.Term.Arg
• expr: Lean.Expr → Lean.Elab.Term.Arg

Auxiliary inductive datatype for combining unelaborated syntax and already elaborated expressions. It is used to elaborate applications.

instance Lean.Elab.Term.instInhabitedArg : Inhabited Lean.Elab.Term.Arg

structure Lean.Elab.Term.NamedArg : Type

• ref : Lean.Syntax
• name : Lake.Name
• val : Lean.Elab.Term.Arg

Named arguments created using the notation (x := val)

instance Lean.Elab.Term.instInhabitedNamedArg : Inhabited Lean.Elab.Term.NamedArg

def Lean.Elab.Term.addNamedArg (namedArgs : Array Lean.Elab.Term.NamedArg) (namedArg : Lean.Elab.Term.NamedArg) : Lean.MetaM (Array Lean.Elab.Term.NamedArg)

Add a new named argument to namedArgs, and throw an error if it already contains a named argument with the same name.
