If that should have the effect described in the discussion, you need
to modify the compilation semantics of DOES> to specify that the DOES>
starts a new definition (currently this is stated only in the
rationale), e.g. as follows:
|6.1.1250 DOES> does CORE
|
|Compilation ( C: colon-sys1 -- colon-sys2 )
|

New stuff between >>> and <<<.
