Using the name: property also works, as in the example below.

I fixed the define implementation so it obeys --no-inline better,
and updated the documentation:

-- Syntax: trace procedure
     Cause PROCEDURE to be "traced", that is debugging output will be
     written to the standard error port every time PROCEDURE is called,
     with the parameters and return value.

     Note that Kawa will normally assume that a procedure defined with
     the procedure-defining variant of `define' is constant, and so it
     might be inlined:
          (define (ff x) (list x x))
          (trace ff) ;; probably won't work
          (ff 3)     ;; not traced
     It works if you specify the `--no-inline' flag to Kawa.
     Alternatively, you can use the variable-defining variant of
     `define':
          #|kawa:1|# (define ff (lambda (x) name: 'ff (list x x)))
          #|kawa:2|# (trace ff) ;; works
          #|kawa:3|# (ff 3)
          call to ff (3)
          return from ff => (3 3)
          (3 3)
     Note the use of the `name:' procedure property to give the
     anonymous `lambda' a name.
