Hi Marcel,

I recently wrote a similar extension method for own purposes:

resumeWithSource: aString

		reparse: aString notifying: nil ifFail: nil;
		resumeUnchecked: self defaultResumeValue

But it does have a different semantic than #retryUsing, which usually takes
a block?

This will work for

[Compiler evaluate: '6 times 7']
	on: SyntaxErrorNotification
	do: [:ex | ex resumeWithSource: '6*7'].

but not for

[Compiler evaluate: '''''''']
	on: SyntaxErrorNotification
	do: [:ex | ex resumeWithSource: ''''''''''].

Changing #parseCue:noPattern:ifFail: so that the initializing calls are also
handled when raising ReparseSourceAfterEditing would solve the problem:

	 doitFlag := noPattern.
	 [self encoder init: aCue notifying: self.
	 self init: myStream cue: aCue failBlock: [^ aBlock value].
	 subSelection := self interactive and: [cue requestor selectionInterval =
(p + 1 to: p + s size)].

	 failBlock:= aBlock.
	 methNode := self method: noPattern context: cue context] 
		on: ReparseAfterSourceEditing 
		do:	[ :ex | ...

However, would this be a good approach?
