Sounds like a compiler to me. Why can't compiled code be
"immediately executed"?
Have you heard of a Just-In-Time (JIT) compiler? It is commonly
used for Java systems that at run-time translate byte-codes
into machine code (in mmeory) and immeditaley execute them.
Same idea, but designed to optimize a specific application (blt).
