ruby-core #94259
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

**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
```
