The PyPy project plans to deliver a compliant language implementation
passing all unit-tests of the current reference C-implementation that are
relevant to the new one. At least 90% of existing unit tests will be directly
-applicable. Moreover, we will be able to add techniques such as JIT compilation
++applicable.[*]_ Moreover, we will be able to add techniques such as JIT compilation
without making the interpreter more complex. Thus we will get speed increases of
2-10 times over the reference C-implementation. We expect algorithmic code to
run at least at 50% of the speed of pure, optimized C code.
+.. [*] The reference C-implementation contains some tests that depend on
+ implementation details. The exact line between a language feature and an
+ implementation detail might at times be hard to draw precisely, but in all
+ cases this only concerns a minority of the tests (less than 10%).
