Well, it depends whether what you want is #part or that particular
combination of #part and #upcase.

Here's a more complete example for String#part:

	x="machin truc patate"
	x.part(7,4).upcase!
	p x #==> "machin TRUC patate"

	y=x.part(4,5)
	p y #==> "in TR"

	y.downcase!
	p y #==> "in tr"
	p x #==> "machin trUC patate"

	y.tr! 'a-z','n-za-m'
	p x #==> "machva geUC patate"

	y[2]="\n"
	p x #==> "machva\ngeUC patate"

	p y.map {|line| "[#{line.chomp}]" }.join
	#==> "[va][ge]"

And it actually works here (after 3 more lines of patching the actual
source).
