Documentation for `Module#const_souce_location` is wrong
Returns the Ruby source filename and line number containing first definition of constant specified.
It should be:
Returns the Ruby source filename and line number containing the last definition (the effective definition) of the constant specified.
It also has an example line:
p Object.const_source_location('A') # => ["test.rb", 1] -- note it is first entry, not "continuation"
but that may give the impression that the first-ness is due to the nature of this method. The reason
["test.rb", 1] is returned instead of
["test.rb", 14] is because the constant is created at line 1, and is only reopened/modified in line 14. Perhaps, this line can be changed to:
p Object.const_source_location('A') # => ["test.rb", 1] -- note 'A' is created in line 1, and is only reopened/modified in "continuation"
Adding something like this may make it clear that it is the last definition that is returned:
D = 'D1' D = 'D2' D = 'D3' ... Object.const_source_location('D') # => returns the location that corresponds to 'D3'
