Subject: [ruby-core:100167] [Ruby master Bug#17193] Endless method definition doesn't work with lambdas

Issue #17193 has been updated by wanabe (_ wanabe).


I think this is an irb problem, not a ruby problem.

```
$ ruby -ve 'def bar() = lambda { |x| x * x };p bar'
ruby 3.0.0dev (2020-09-25T22:52:04Z master 137fa5b27e) [x86_64-linux]
#<Proc:0x00005582978039e0 -e:1 (lambda)>
```

----------------------------------------
Endless method definition doesn't work with lambdas. Please check the attached screenshot.

``` ruby
def foo() = 123
# => :foo

foo
# => 123

def bar() = lambda { |x| x * x }
# I expected the method to be defined.

def bar() = ->(x) { x * x }
# Same issue.
```

Nice to have:

``` ruby
def bar = lambda { |x| x * x }
def bar = ->(x) { x * x }
```
