* src/mes.c (t): Add TVARIABLE. (scm_vm_eval_deref): New vm special. (make_vref_): New internal function. (eval_apply): WIP: replace symbols with their variable reference. * src/gc.c (gc_loop): Handle TVARIABLE. * src/lib.c (display_helper): Handle TVARIABLE. * module/mes/type-0.mes (<cell:variable>): New variable. (cell:type-alist): Add it. (variable?): New function. * module/mes/display.mes (display): Handle <variable>.
