That just means compiling it at the time the constructed statement is submitted for execution, then executing the generated code.  No problem so long as the compiler is available at run time.  PDP-10 TECO did that (it has the same feature, executing a string buffer full of commands).  So does Python, and I suspect it solves it the same way.
