[ruby-core:87473] [Ruby trunk Feature#14680] Adding +@ and -@ to hash and array

Issue #14680 has been updated by Hanmac (Hans Mackowiak).


we need to specify it, that `-@` and `+@` are not doing deep freeze (they don't freeze the values of hash or elements of array)

people might do this:

~~~ ruby

VAL = -["abc"]
~~~

and suspect the string inside the array to be frozen too

or are we asume now that frozen-string-literal is true for this?

----------------------------------------
Since we have `-@` and `+@` for strings and it's very useful (and reads better than `.freeze`) I'd like to propose adding the same API to hash and array. Especially with constants, linters are always telling me to freeze them, and I'd like to be able to accomplish that with `-@`. I've attached the necessary code to make that happen.
