Using let variable in before(:all) hook, example store let variable in each scope and it break rspec test.

I think this is a bug. and should not store let variable.

this is demo spec.

This has already been fixed in 2.13.1, although we've never intended to support calling a let from before(:all). In 2.13.1 we've added a deprecation warning since a fair number of users have been doing this even though there's no reasonable, non-confusing semantics for how these things could be combined.

Here's the output from that demo spec on 2.13.1:

Rspec Tests Evaluation
WARNING: let declaration `test` accessed in a `before(:all)` hook at:
  /Users/myron/code/rspec-dev/repos/rspec-mocks/spec/rspec/mocks/at_most_spec.rb:96:in `block (2 levels) in <top (required)>'

This is deprecated behavior that will not be supported in RSpec 3.

`let` and `subject` declarations are not intended to be called
in a `before(:all)` hook, as they exist to define state that
is reset between each example, while `before(:all)` exists to
define state that is shared across examples in an example group.

  when set variable by let
    should eq 401
  when set variable by let too
    should eq 200
