reserved_words : unit -> string list

SYNOPSIS

Returns the list of reserved words.

DESCRIPTION

Certain identifiers in HOL are reserved, e.g. `if', `let' and `|', meaning that they are special to the parser and cannot be used as ordinary identifiers. The call reserved_words() returns a list of such identifiers.

FAILURE CONDITIONS

EXAMPLE

In the default HOL state:

  # reserved_words();;
  val it : string list =
    ["("; ")"; "["; "]"; "{"; "}"; ":"; ";"; "."; "|"; "let"; "in"; "and";
     "if"; "then"; "else"; "//"]
