this is analogous to what we do for const aaa = bbb, ccc = ddd; in typescript, where there is one scope for each subclause and one scope for the entire statement

This concept is supported in a few languages other than Python. Here's more info, courtesy of chatgpt:

Several languages have constructs similar to Python's with statement, designed for managing resources in a structured way. Here's a closer look at how some languages implement this with ___-style setup:

1. C# (.NET Framework):

   • Construct: using
   • Usage: with equivalent in C# is using. It's used for managing resources like file streams, network connections, or database connections. It ensures the resources are disposed of once the block is exited.
   • Example:

     using (var resource = new Resource())
     {
         // Use resource
     } // Automatic disposal of resource

2. Java:

   • Construct: try-with-resources
   • Usage: Introduced in Java 7, try-with-resources is similar to Python's with. It ensures that each resource is closed at the end of the statement.
   • Example:

     try (Resource resource = new Resource()) {
         // Use resource
     } // Automatic resource closure

3. VB.NET:

   • Construct: Using
   • Usage: Similar to C#, VB.NET uses Using for managing and disposing of resources automatically.
   • Example:

     Using resource As New Resource()
         ' Use resource
     End Using ' Automatic disposal of resource

4. Swift:

   • Construct: defer
   • Usage: While not a direct equivalent, Swift's defer statement schedules code to be executed when the current scope is exited, similar to the cleanup part of Python's with.
   • Example:

     let resource = Resource()
     defer {
         resource.close()
     }
     // Use resource

5. F#:

   • Construct: use
   • Usage: F# has a use keyword that is similar to using in C#. It's used for automatic disposal of resources.
   • Example:

     use resource = new Resource()
     // Use resource

These constructs are primarily used for resource management to ensure that resources such as file handles, network connections, or database connections are properly released after their use, even if an error occurs. Each language has its own syntax and nuances, but the underlying principle remains the same.

Looks like C#, Java, and VB.NET are good matches, where name and value could be defined similarly to what we've done here for Python. The others are a bit more dicey

Yeah, Java's try-with-resources was the first one to come to mind other than Python.

Don't forget the ECMAScript explicit resource management proposal

ok @AndreasArvidsson this one has been updated based on our discussion

Note that CI will fail until #2206 is merged
