Addendum.

Regarding MRB_CI_COMPANION_BLOCK, this patch uses “companion” as the opposite of “orphan”.
However, I don't know the exact term, nor do I have any evidence for it.
So I hope you will change MRB_CI_COMPANION_BLOCK to the correct name.

[dearblue]

One more addition.

The current MRB_PROC_ORPHAN is 512.

So, to make it “orphan” when creating the proc object,

• MRB_PROC_ORPHAN = 0.
• MRB_PROC_COMPANION = 512 (name is temporary)

There may be a future with such a change.

There was a problem with this patch.
If passed as block arguments in another method call from the generating call frame, the break would not cause a LocalJumpError.

b = proc { break "BAD!" }
p self.tap { b.call }
# (expected)          => break from proc-closure (LocalJumpError)
# (after this patch)  => "BAD!"

I would like to revert or find a way to fix it.
Please give me some time. I'm sorry.
