Subject: [ruby-core:59445] [ruby-trunk - Bug #9335][Open] dynamic rescue	regression in Ruby 2.1


Issue #9335 has been reported by fdr (Daniel Farina).

----------------------------------------
Bug #9335: dynamic rescue regression in Ruby 2.1
https://bugs.ruby-lang.org/issues/9335

Author: fdr (Daniel Farina)
Status: Open
Priority: Normal
Assignee: 
Category: 
Target version: 
ruby -v: ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-linux]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN


The following type of rescue block appears broken:

begin
  raise 'hello'
rescue ->(e) { true }
end

In Ruby 1.9.3p484, this exits with a normal exit code and no output.

On Ruby 2.1.0, it instead yields:

/tmp/badin21.rb:4:in `rescue in <main>': class or module required for rescue clause (TypeError)
	from /tmp/badin21.rb:2:in `<main>'

Some research suggests this is a regression to the pre-1.9.2 behavior, and there doesn't seem to be any direct mention about this change in the changelog of 2.1 nor 2.0.
