help?> methodswith
search: methodswith

  methodswith(typ[, module or function][, showparents])

  Return an array of methods with an argument of type typ.

  The optional second argument restricts the search to a particular module or 
function (the default is all modules, starting from Main).

  If optional showparents is true, also return arguments with a parent type of 
typ, excluding type Any.
