Good list. Let's review them. Cuis is open for enhancements! Please 
don't take Cuis like carved on stone. Let's enhance it together!

1)
String >>indexOfSubCollection: sub startingAt: start ifAbsent: 
exceptionBlock
instead of: String >> indexOfSubCollection: sub

I'll add this method today. I see no reason for not having it.

2)
String crCharacter
instead of: String cr

String lfCharacter
instead of: String lf

String crlfString
instead of: String crlf

 The reason for all these was to enable and test the conversion to LF 
convention for Cuis. I wanted to know which senders of #cr and such 
wanted a Character and which wanted a String. Naming the methods the 
same is "false plymorphism". But the conversion to LF is already done, 
and this affects compatibility for no good reason. There are 2 
possibilities here: a) add #cr, #lf, #cflf, etc as compatibility 
methods, or b) remove #crCharacter and such, changing senders back. 
Opinions?

3)
Smalltalk at:
instead of: Smalltalk globals at:

This one is easy. In Cuis, #globals should answer self. A similar trick 
for SmalltalkImage current and such. All these can simply answer Smalltalk.

Everybody, please tell your opinion about these stuff and the options. 
And keep posting such gracious compatibility issues so we can address them.

Cheers,
Juan Vuletich
