I use this all the time in a database engine I am using at work. It
supports stored procedures in its own funky language and the whole
thing can be compiled, but there is a language construct which allows
one to run code directly even from within a compiled file. I use this
a lot for debugging and trying out new code because it spares me from
compiling with every little change.

I think the way they do it is they include the language parser with
the virtual machine which handles the bytecode-compiled application.
Both seem to work nicely together and operate in the same scope and
namespace, so for example one can spawn a dialog at runtime, type in
some code to be executed, and resume execution, and the parsed code
will have integrated well (variables, data etc.)
