Bug #16506
closedDocumentation for `Module#const_souce_location` is wrong
Description
https://ruby-doc.org/core-2.7.0/Module.html#method-i-const_source_location says:
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'
