Issue #16469 has been updated by jeremyevans0 (Jeremy Evans).


We can probably use `__callee__` instead of hard coding the method names, that should fix this issue:

# Sample code
``` ruby
enc_uri = URI.encode("http://example.com/?a=\11\15")
URI.decode(enc_uri)
```

# Actual
```ruby
irb(main):005:0> enc_uri = URI.encode("http://example.com/?a=\11\15")
(irb):3: warning: URI.escape is obsolete

irb(main):006:0> URI.decode(enc_uri)
(irb):6: warning: URI.unescape is obsolete
=> "http://example.com/?a=\t\r"
```

# Expected
Print `warning: URI.encode is obsolete` and `warning: URI.decode is obsolete` . (or no warnings)
