An example where that could be useful is in validating an emulation. I did
that recently: running an EL-X8 emulation implemented in ALGOL (by Dick Gruene)
on an EL-X8 emulation in SIMH. Run the test program that comes with it both on
the nested emulation, and "standalone" on the outer emulation. Compare the
outputs from the two runs, and fix or justify any differences. It helped
significantly, especially because the inner emulation came with a bunch of
important details about strange machine quirks.
