Without altering the current set of priorites for GCL development I would
like to note that two classic application areas for LISP are the modelling
of visual and neurological processes, both of which I would expect to
benefit substantially from optimised floating point loops (eg neural
networks and the application of mexican hat filters to images).
As usual I feel constrained to point out that I don't do these things myself
but I believe that language implementors need to look to likely application
areas and there seems to have been an historical need to compare LISP to
Fortran for array and numerical processing.
