Hi
Are the following differences intentional?
```
$ ruby -v
ruby 2.7.0dev (2019-03-18 trunk 67291) [x86_64-darwin18]
```
```
$ cat ptn1.rb
a = -> { p @1 }
a.call(1)
$ ruby ptn1.rb
Traceback (most recent call last):
1: from ptn1.rb:2:in `<main>'
ptn1.rb:1:in `block in <main>': wrong number of arguments (given 1, expected 0) (ArgumentError)
```
```
$ cat ptn2.rb
a = lambda { p @1 }
a.call(1)
$ ruby ptn2.rb
1
```
thanks

Issue #15672 has been updated by shevegen (Robert A. Heiler).
Koichi said it will be fixed. :)
(I guess this was never intentional, thus a bug.)
