In the original Smalltalk, blocks were almost but not quite closures.

Thanks, all. Now I'm understood differences.

Why is this particularly hard for smalltalk? Scheme implementations
manage to do it. Is it simply that it's an afterthought, when it needs
to be designed in from the ground up?

Two common problems I observed are related to:
(1) Smalltalk inlines some blocks, such as the ones involved in
What difference between this things. I know about Eliots post
describing closures in Squeak, but it's too massive and so special to
understand.
Thanks.

Briefly, A closure tracks the full computational state of its block.
A block is a executable

Not necessarily. I could see an implementation where i would be 4.
