Thanks! These look fine; I've now incorporated them into the main repository.

One thing: I mentioned a replaceWith: idiom as an eventual possibility, not as a concrete immediate 
suggestion. I rolled your replaceWith: idiom into our existing equivalent replaceFrom: methods. I'll 
refactor them all at once when/if the time comes, but I wanted to avoid protocol duplication so they're 
gone for now.
