Thanks.  contrib/ doesn't receive much love when it comes to these sorts
of things, and byte-compiling its files is not a pretty sight.

A "contrib: " prefix on this subject would be useful for orienting log
readers.

Convention nit-pick: Drop the period from the subject.

The byte-compiler complains after your change:

    contrib/lisp/ob-tcl.el:129:1:Warning: the following functions are
        not known to be defined: case, output, value

These all come from a missed s/case/cl-case/.

Same applies here.  You took care of s/position/cl-position/ below, but
there are a good number of other symbols that now require a prefix:
defstruct, destructuring-bind, incf, pushnew, first, and second.

I haven't yet looked beyond the first two files, though I suspect the
other files may have similar issues.  Could you take a closer look and
send an updated patch?
