[Cuis] Ropes (functional strings)

[H. Hirzel]

Congrats to this implementation, Ken

In particular I like how you did

Rope>>doesNotUnderstand:

doesNotUnderstand: aMessage

	"See what is missing from Ropes"
	Transcript log: (String streamContents: [:s | aMessage storeOn: s]).
	
	"Do what a String would do"
	aMessage sendTo: (self asString)


and then


Rope class>>openTextEditor


openTextEditor

"
	Rope openTextEditor.
"
	SystemWindow
		editText: (TextModel
			withText: (FlatRope fromString:
                               'Let us see what these Rope things can do.'))
			label: 'Text Editor'
			wrap: true


Kind regards

Hannes
