Hi Alexandre,

Because what we call a block is actually a closure. Smalltalk-80 invented blocks, which were not closures at that time. Over the time we found out that Blocks are not really useful, but instead the humanity largely prefer closure.

I don't think this is right. ��Yesterday Cl��ment and I had lunch with Dan Ingalls and we talked about the origin of blocks. ��At first blocks were not even real objects; instead they were just a syntactic construct for delayed evaluation. ��Over time the original Smalltalk team found they needed more and more useful features, and they wanted everything to be objects so they introduced both the syntax for blocks and the class BlockContext, but they didn't look at other languages and so they didn't implement blocks as closures.

So I think its more accurate to say
�� ��Over time Smalltalkers found blocks were /really/ useful. ��Later on they found out that they could implement blocks as closures, with the result that they were even more useful and much cleaner, leading to a more efficient virtual machine.

But ok, this is not a pressing thing. Was just a tough.

If it ain't broke don't fix it. ��The name BlockClosure isn't incorrect. ��These are blocks implemented as closures. ��The name MethodContext /is/ broken. ��These /aren't/ just MethodContexts any more, they are both BlockContexts and MethodContexts, so collapsing ContextPart and MethodContext together into just Context, and deleting the now unused BlockContext does make sense.
