We want to be able to easily evaluate a block in the context of a specific object.

Gregg suggested the word WITH, as in:

with object [a: 10 ....]

That is a good suggestion, similar to VID2 usage of WITH.

I also suggested IN, mainly because I did not want to add a new word...

in object [a: 10 ....]

But, that does make IN do two things that are related, but not identical. (Word bind, and bin block plus evaluate it).

Another option is to write:

do in object [a: 10 ....]

Now IN is consistent, but that's more to type, and programmers don't like typing.

We could also have:

do/in object [...]

But, it's more problematic: 1) it reverses the DO arg order, 2) it slows down DO for everything, just a tiny tiny bit.

It's worth nothing that this function is equivalent to:

do bind/deep/copy [...] object

So, we have the option of of just keeping that. But that format is not as friendly.
