Bug #13090: Cannot use return statement in lambdas using instance_eval (MRI 2.4)
https://bugs.ruby-lang.org/issues/13090
* Author: Nikita Shilnikov
* 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
----------------------------------------
Hello,
I'm pretty sure I've found a bug after running specs for dry-initializer gem on MRI 2.4.
I managed to find the minimal code to reproduce the issue:
MRI 2.3.3
`
$ ruby -e "instance_eval(&lambda { |_| return })"
$
`
MRI 2.4.0-p0
`
$ ruby -e "instance_eval(&lambda { |_| return })"
-e:1:in `block in <main>': unexpected return (LocalJumpError)
from -e:1:in `instance_eval'
from -e:1:in `<main>'
`
I _think_ lambda has been converted to an ordinary proc, but I didn't check it.
Best regards,
Nikita
