what is XCL?

[Sam S. <sd...@gn...>]

Hi Bruno,
CLISP test suite mentions XCL a lot.
Moreover, it contains 3 files (readtable, tread, tprint) which are
_only_ used with XCL.
Comments seem to indicate that XCL might be a German implementation from
the 1980-ies.

Could you please shed some light on this?
Do we need it?

Thanks.

Yes, the clisp/tests/README gives credit to its authors.

Some of the bibliography at https://www.informatik.uni-kiel.de/~wg/New/MoreTechReports.html
is probably related.

It is not the same as http://www.cliki.net/XCL .

You can surely remove the #+XCL result cases.

Before removing the files readtable.tst tread.tst tprint.tst, I would first try
to adapt them to clisp and sbcl (unless the ansi-tests or sacla-tests already
contain comprehensive tests of these areas). Remember, the goal is to uncover
bugs.
