[Squeakfoundation]ContextCleanupPlus-ajh (was: Re: KCP & 3.6)

[Daniel Vainsencher]

[Additions to various classes...]
Note that my problem with these is not that I argue with the usefulness
of specific items - I simply don't think that it's appropriate to
include them as part of a fix. Why don't you post them one by one to the
mailing list for discussion, where people may argue whether they are
appropriate. You're saying that something should be part of the class
library, defend your opinions on squeak-dev, just like Richard does,
method by method, idea by idea.

[... are mostly required by closures, not runtime fixes]
Great. Then can you please isolate only those needed for the runtime
fixes? it'll mean we have a lot less to talk about before including the
runtime fixes in the image. Then we'll only need a review by someone
with exceptions savvy...
