* The Debug API relies upon a field called ``savedpc`` which tracks the current instruction being executed by Lua interpreter. As this is not updated by the JIT code the Debug API can only provide a subset of normal functionality. The Debug API is not yet fully tested.
* The Lua VM supports infinite tail recursion. The JIT compiler treats OP_TAILCALL as normal OP_CALL so that recursion is limited to about 110 levels.
* The Lua C API has not yet been tested against the Ravi extensions - especially static typing and array types. Do not use the C API for now - as you could break the type system of Ravi.
* Bit-wise operators are not yet JIT compiled.
Future Performance Enhancements
-------------------------------
The main area of enhancement is to provide specialised versions of Lua FORNUM loops so that the generated code is more efficient and is moreover recognised by LLVM as a loop.

When values from a function call are assigned to a typed variable, an implicit type coersion takes place. In above example an error would occur if the function returned values that could not converted to integers.
In the following example, the parameter ``j`` is defined as a ``number``, hence it is an eror to pass a value that cannot be converted to a ``number``::
