((lambda (x) (print x)) "hello, world!") is just a fancy way of
FUNCALLing the lambda function.  This way is more efficient (the
compiler just inlines it) is what Paul Graham says in On-Lisp.

I agree.  An API change is the best option.  I can't believe I even
came up with such an outlandish suggestion.  I blame CL.  What I
suggested wouldn't be possible in another language (Perl is the only
other mainstream language I don't know, so I wouldn't know about it)
:-)

I'll check out the latest versions of LoGS tomorrow.
