Issue #9047 has been updated by rosenfeld (Rodrigo Rosenfeld Rosas).


I'd prefer to reserve this syntax as a short hash syntax for string keyed hashes:

{
 'string': 'v' # equivalent to 'string' => 'v'
}

If your proposal is accepted, then it wouldn't be possible add the short syntax support for strings.

Do you have any real-world use case where a symbol would be useful but you need the :'xxx' constructor to generate it? I don't think this is a common thing to happen...

Feature #9047: Alternate hash key syntax for symbols

In Ruby, if you can create a symbol with ((|:"symbolname"|)), it seems consistent to allow moving the colon to the right side in a hash and dropping the hash rocket (=>).


 {
   :str => "v",   # symbol
   str: "v",      # symbol
   :"str" => "v", # symbol
   "str": "v",    # should also be a symbol
 }
 
 
It would look like this:

 h = {
   "mykey": "value",
   "otherkey": "othervalue",
   regular_symbol: "value"
 }

String and other non-symbol keys would retain the hash rocket syntax to avoid ambiguity.

 {
   "string" => "v",
   MyObj.new => "v",
   @my_var => "v"
 }

Thoughts?
