Bug #18878: parse.y: Foo::Bar {} is inconsistently rejected
https://bugs.ruby-lang.org/issues/18878#change-114482
* Author: qnighy (Masaki Hara)

* ruby -v: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux]
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
The following source doesn't parse:
```ruby
Foo::Bar {}
```
despite the following:
```ruby
bar # local variable or method call
Bar # constant
bar() # method call
Bar() # method call
bar {} # method call
Bar {} # method call
bar() {} # method call
Bar() {} # method call
Foo::bar # method call
Foo::Bar # constant
Foo::bar() # method call
Foo::Bar() # method call
Foo::bar {} # method call
# Foo::Bar {} # SyntaxError
Foo::bar() {} # method call
Foo::Bar() {} # method call
```
Especially considering `Bar {}`, this looks like a missing implementation rather than an intentional behavior.
