Sure. Something like this:

function my_rebin, a, $
arg0, arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9
;continue to heart's content

narg = n_params()-1
command = 'result = round( rebin( float(a)'
for i = 0, narg-1 do begin
command = command + string(', arg',i,format='(a,i0)')
endfor
command = command + ') )'
junk = execute(command)
return, result
end

I imagine there are limits placed on this technique by the maximum
number of arguments to an IDL procedure, or the maximum length of a
string EXECUTE can handle.
