Subject: [ruby-core:94259] [Ruby master Feature#16095] 2 Features: remove (simplify) 'new' keyword and Property Shorthand

Issue #16095 has been updated by shevegen (Robert A. Heiler).


The net-gain from removing .new would be quite minimal. I also think it is less
readable too, but even well aside from this, this seems to be backwards
incompatible and may have to require a long transition time if it is possible
to add. I am also not sure whether matz would want to have this - IMO there are
too many drawbacks associated with the change, with the net benefit of writing
shorter code being a very minimal advantage, if it is one at all.

Property Shorthand was discussed before; matz responded back then. I believe
what he wrote back then still applies. (I don't remember offhand but I think
one comment from matz was to wait and see; I think that was in regards to
javascript and how they use their shorthand variant.)

It may be better to add to the discussion at #15192 if you feel strongly about
shorthand syntax.

As for other syntax such as:

    :arg1, ^arg1, %arg1, ...)

I think some of them are problematic. First one is symbol - I think people would
not expect a symbol to behave as a shortcut syntax in this context. But either way
I think it is best to discuss this at #15192, IMO.

----------------------------------------
Feature #16095: 2 Features: remove (simplify) 'new' keyword and Property Shorthand
https://bugs.ruby-lang.org/issues/16095#change-80574

* Author: D1mon (Dim F)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
**common use:**
``` ruby
class A
  def initialize(arg1, arg2)
    @arg1 = arg1
    @arg2 = arg2
  end
end
A.new(1,2)
```

1) feature: remove 'new' keyword:
``` ruby
A(1,2) # shorter and more comfortable
```


2) feature: Property Shorthand (like ES6)
``` ruby
class A
  def initialize(arg1, arg2)
    # shorter and more comfortable
    @arg1, @arg2
    # or this:
    @arg1
    @arg2
  end
end
```


So as not to duplicate the code (words). May need to do some other syntax or character (:arg1, \^arg1, %arg1, ...)

can also be applied to other types.

Hash example:
``` ruby
a = 1
b = 2
h = {a:a,b:b} # common use
h = {a,b} # new syntax or {%a,%b} - any syntax of your choice
```
