to_s

        # UnboundMethod.to_s

(from ruby core)
---
    to_s()

---

Returns a human-readable description of the underlying method.

    "cat".method(:count).inspect   #=> "#<Method: String#count(*)>"
    (1..3).method(:map).inspect    #=> "#<Method: Range(Enumerable)#map()>"

In the latter case, the method description includes the "owner" of the
original method (`Enumerable` module, which is included into `Range`).

`inspect` also provides, when possible, method argument names (call
sequence) and source location.

    require 'net/http'
    Net::HTTP.method(:get).inspect
    #=> "#<Method: Net::HTTP.get(uri_or_host, path=..., port=...) <skip>/lib/ruby/2.7.0/net/http.rb:457>"

`...` in argument definition means argument is optional (has some
default value).

For methods defined in C (language core and extensions), location and
argument names can't be extracted, and only generic information is
provided in form of `*` (any number of arguments) or `_` (some
positional argument).

    "cat".method(:count).inspect   #=> "#<Method: String#count(*)>"
    "cat".method(:+).inspect       #=> "#<Method: String#+(_)>""
