...and maybe other.
a = {
nodeA: 'abc',
nodeB: 'def'
}
And b = a.concat('123')
b = {
nodeA: a, /* {
nodeA: 'abc',
nodeB: 'def'
} */
nodeB: '123'
}
So in the simplest case the VM has to do nearly no work. The only problem is that this slows down...

Scratch that! Today I ran into a problem: ...
Break a previous commit into multiple commits
...was farther back in the tree than you want to count, then
$ git rebase -i 123abcd~
where 123abcd is the SHA1 of the commit you want to split up.
If you are on a different branch (e.g., a feature branch) that you plan to merge into master:
$ git rebase -i master

On the other file..
