The present invention relates to systems and methods that facilitate dynamic programming language execution in a managed code environment. A runtime code generator is provided within the framework of a managed object environment. The code generator includes a class allocator that reserves one or more method slots for a dynamic method call. A dynamic method builder then employs the method slots to generate an intermediate language stream that forms a method description. The method description is then fed to a Just-In-Tine (JIT) compiler that returns at least one dynamically generated pointer to facilitate execution of the dynamic method call at runtime.
