Many languages provide features to help with releasing system resources, such as open file handles. For example, C# has the using statement which works with IDisposable interface. Go has the defer keyword. Java has a try-with-resources statement that works with the AutoCloseable interface.

One key area in Ballerina which could take advantage of this is the SQL connections and streams.

This is related to #334, but not quite the same.

One important design issue is whether the method that gets calls (i.e. our equivalent of IDisposable or AutoCloseable) can return an error. I suspect it needs to, and then it will automatically do a check on that.
