Bug #15672: Lambda implicit arguments, differences between lambda {} and -> {} specifications
https://bugs.ruby-lang.org/issues/15672#change-77132
* Author: takeshinoda (Takeshi Shinoda)
* Status: Open

* Target version:
* ruby -v: ruby 2.7.0dev (2019-03-18 trunk 67291) [x86_64-darwin18]
* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
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
