In order to allow converting an opaque object instance to an arbitrary (jsii-managed) interface type, the `UnsafeCase` operation may be used to instantiate a proxy while bypassing all type consistency checks. This is similar to using `as any` or `as T` in TypeScript, meaning that if the user performs a cast to an incorrect/unsupported type, undefined behavior follows. This would unblock certain specific use-case scenarios that static languages render difficult to enact, such as the one described in aws/aws-cdk#3284.

In order to allow converting an opaque object instance to an arbitrary
(jsii-managed) interface type, the
UnsafeCaseoperation may be used toinstantiate a proxy while bypassing all type consistency checks.
This is similar to using
as anyoras Tin TypeScript, meaning thatif the user performs a cast to an incorrect/unsupported type, undefined
behavior follows.
This would unblock certain specific use-case scenarios that static
languages render difficult to enact, such as the one described in
aws/aws-cdk#3284.
In particular, this is the only way out until aws/aws-cdk-rfcs#193
is delivered, for dealing with instances of interfaces returned through
a type union API.
