ruby -v set to ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
----------------------------------------
Bug #13087: Regression of instance_exec behaviour in ruby 2.4
https://bugs.ruby-lang.org/issues/13087#change-62317
* Author: Tiago Cardoso
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
I've just caught up this running our test suite against the newly released ruby 2.4. Here is the repro gist:
```ruby
class A
def initialize(x)
@x = x
end
def perform
puts "performing #{@x} times"
end
end
puts "basic"
A.new(1).tap do |a|
a.instance_exec do
perform
end
end
#puts "advanced"
A.new(1).tap do |a|
a.instance_exec(A.new(3), &:perform)
end
```
The last one output "3 times in all ruby 2's except latest 2.4 .
This seems to apply the to_proc symbol to the object itself, and not the argument of instance_exec, which is a regression.
