Subject: [ruby-core:119862] [Ruby master Feature#20882] Provide Boolean(...)

Issue #20882 has been updated by murb (Maarten Brouwers).


+1 for the request, I don't like to resorting to `ActiveRecord::Type::Boolean.new.cast(value)` to cast booleans. I would prefer a more explicit `.parse` which DateTime has though:

```
DateTime.parse("2021-04-13T14:20")
```


```
Boolean.parse("0") # false
Boolean.parse(1) # true
Boolean.parse("t") # true
```

Feature #20882: Provide Boolean(...)
https://bugs.ruby-lang.org/issues/20882#change-110552

* Author: getajobmike (Mike Perham)
* Status: Open
----------------------------------------
Ruby provides Integer(...) and Float(...) global methods to coerce values. Is there a similar method for Booleans?

I'd like to do something like:

```
# ENV["SOME_FEATURE"] is unset
Boolean(ENV["SOME_FEATURE"]) # => false

# ENV["SOME_FEATURE"] is unset, but allow a default?
Boolean(ENV["SOME_FEATURE"], true) # => true

# explicitly disable
ENV["SOME_FEATURE"] = "0"
Boolean(ENV["SOME_FEATURE"], true) # => false

# explicitly enable
ENV["SOME_FEATURE"] = "1"
Boolean(ENV["SOME_FEATURE"]) # => true
```
