Thank you, Helmut.  This works fine.  Femlisp loads, and I am left with
an "APPLICATION>" prompt.

I tried to set the package in the file being loaded, but it did not work
because *PACKAGE* is specially bound during LOAD.

I have tried it now again with CMUCL and I could not reproduce this error,
i.e. when I do `M-x slime', *READ-DEFAULT-FLOAT-FORMAT* remains at
'DOUBLE-FLOAT.  Fine.  However, I see that the package of the REPL is reset
to CL-USER.  For me, it would be better if it remained FL.APPLICATION.

Or should I use a different function for bringing up the SLIME-REPL buffer?

Thank you very much,

Niko.
