Guys,
In a deep inheritance tree, is there an easy way to determine the origin
or source (module, class) of a method?
Thanks,
John

a) Use fri (fast-ri)
b) Use Method#inspect, example: [].method(:find) # => #<Method:
Array(Enumerable)#find>

b) seems to assume an irb environment that calls .inspect automatically.
Try:
puts [].method(:find).inspect
New question: Parsing the (Enumerable) out would be tacky, so how do we
do
what .inspect was doing when it built that string for us?

If you’d like something better than this, then vote for the
Method#owning_class (or better name) aspect of RCR 15.
Disclaimer: I proposed that particular RCR.

Nodewrap can do it:
irb(main):001:0> require ‘nodewrap’
=> false
irb(main):002:0> Hash.instance_method(:map).origin_class
=> Enumerable
