 3. Bridge `suspend` and context parameters features together, making the language to work as a whole
 
 The proposal is to treat all `suspend` functions

-suspend fun computation() = /* implicitly enclosed within */ context(getContinuation_compiler_intrinsic().context) {

 context(_: CoroutineContext)

+The code above works because the compiler encloses the `suspend` function body within the `context` block:

+```kotlin
+suspend fun computation() = context(getContinuation_compiler_intrinsic().context) {

+}

 ### `coroutineContext` stdlib property
 
 Currently, `suspend` properties are disallowed to encourage users to declare only such properties which are cheap to compute.
