-// Local functions are compiled to private static functions on the class
-// containing the local funtion. This has a number of consequences observable
-// from a debugging perspective, for this test specifically:
-//   - local functions do not figure in the LVT of the outer function, as they
-//     are not instantiated.
-//   - the _declaration_ of the local function does not figure in the byte code
-//     of the outer function and hence, has no line number
-//   - captures are treated differently, according to the implementation
-//     strategy: on the IR, captures are passed as arguments to the static
-//     function, on the old backend, they are added to fields on the lambda
-//     object. Hence, for debugging purposes, captures are "just"
-//     variables local to the function, and hence need no name mangling to
-//     properly figure in the debugger.
