     Type checker will allow inferred types for holes.
 
 A partial type signature is a type signature containing special
-placeholders written with a leading underscore (e.g., "``_``",
-"``_foo``", "``_bar``") called *wildcards*. Partial type signatures are
-to type signatures what :ref:`typed-holes` are to expressions. During

 Unlike :ref:`typed-holes`, which make the program incomplete and will
 generate errors when they are evaluated, this needn't be the case for
