Thank you for explaining what "Source-based code replication" means.

It's obvious to me.  Source-based code replication such as
EVALUATE-based macros or MPEs earlier inliner has a number of
problems, discussed in
<http://www.complang.tuwien.ac.at/forth/why-evaluate-is-bad>.

E.g., the names are not bound statically as usual in Forth, but it
depends on the dictionary and search order state in the place where
the code is replicated to.

For your sorting, you use that as a feature, by having different
COMPARE definitions visible at the point of replication, but that is
unidiomatic in Forth.  We do not pass parameters by defining certain
named words in the search order, and then letting the user of the
parameter look it up (in Postscript this is idiomatic, but PS uses
dynamic name binding).  In Forth we pass parameters on the stack.

But even if we accept passing of the COMPARE parameter by search
order, the source-based code replication means that you have a large
number of additional parameters: all the words whose names occur in
the source.  In addition, if numbers with more than one digit occur,
you have BASE as a parameter, and other state variables that are used
when compiling the source code.
