Subject: [ruby-core:106982] [Ruby master Feature#18460] implicit self for .() syntax without rvalue

Issue #18460 has been updated by matz (Yukihiro Matsumoto).

Status changed from Open to Rejected

This proposal is rejected for several reasons:

* we don't allow `.m` notation for implicit self (for now at least)
* You will gain only 4 fewer characters
* I don't think it's worth the cost of syntax complexity it brings

Matz.

Feature #18460: implicit self for .() syntax without rvalue
https://bugs.ruby-lang.org/issues/18460#change-95812

* Author: cvss (Kirill Vechera)
* Status: Rejected
* Priority: Normal
----------------------------------------
We have a nice `.()` shorthand for calling Proc

```ruby
m = 1.method(:+)
m.(2) # 3
```

But while we can use this shorthand in a Proc's context with the explicit self, we cannot use it with the implicit self:
```ruby
m.instance_exec { self.(2) } # 3
m.instance_exec { .(2) } # syntax error, unexpected '.' (SyntaxError)
```

So I propose to make this syntax valid too.
