inductive Lean.Elab.Term.Arg : Type

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

• stx (val : Syntax) : Arg
• expr (val : Expr) : Arg

instance Lean.Elab.Term.instInhabitedArg : Inhabited Arg

structure Lean.Elab.Term.NamedArg : Type

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

• ref : Syntax
• name : Name
• val : Arg
• suppressDeps : Bool

  If true, then make all parameters that depend on this one become implicit. This is used for projection notation, since structure parameters might be explicit for classes.

instance Lean.Elab.Term.instInhabitedNamedArg : Inhabited NamedArg

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

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