[plt-scheme] Expanding into this-expression-file-name

Hi all,

I have a macro that expands into this-expression-file-name.
 I want the file name of the point of use, but I get the
file name of the point of definition.  How do I get the
macro to use the source information of the expansion point?
 Current code below.

Thanks,
Noel

  ;; syntax this-expression-benchmark-log-file : () -> path
  (define-syntax (this-expression-benchmark-log-file stx)
    (syntax-case stx ()
      [(this-expression-benchmark-log-file)
       ;; result is the same w/ just syntax instead of
syntax/loc
       (syntax/loc stx
         (build-path
          (this-expression-source-directory)
          (string-append
           (path->string (this-expression-file-name))
           ".benchmark-log")))]))
