Subject: [ruby-core:87026] [Ruby trunk Feature#14249] Remove str[match_str]

Issue #14249 has been updated by gotoken (Kentaro Goto).


A use in replament may look intuitive.

```
s = "Cage"
s["age"] = "heese"
p s
#=> "Cheese"
```

Feature #14249: Remove str[match_str]

I wonder if `str[match_str]` makes sense.

``` Ruby
"ana"['a'] => "a"

```

I would say this is not expected and it brings problems, for example when accessing nested hashes. For example:

``` Ruby
params = { "user" => "Nicolas Cage" } => {"user"=>"Nicolas Cage"}

params["user"]["age"] => "age"

```

I think `str[regexp]` is enough and that `str[match_str]` can be removed.
