----------------------------------------
Feature #19232: add NoMatchingPatternError#matchee
https://bugs.ruby-lang.org/issues/19232
* Author: dalexj (alex jensen)
* Status: Open
* Priority: Normal
----------------------------------------
currently if you pattern match a Hash, you can inspect the #key and #matchee methods from the NoMatchingPatternKeyError
```ruby
begin
{ error: true } => { value: }
rescue NoMatchingPatternKeyError => e
e.matchee
end
# => {:error=>true}
```
I would find it very helpful for this functionality to be available for the standard `NoMatchingPatternError` without hash key matching
proposed:
```ruby
begin
[:error, "message"] => [:ok, value]
rescue NoMatchingPatternError => e
e.matchee
end
# => [:error, "message"]
```
