If not, then there's nothing more I need to do. If you do, I could catch them and do the deferring.
On SBCL, CCL, and more, when a forward reference is detected, it is assumed to be a function. If defined later as a function, the warning is dropped. If redefined later as a macro, that's a warning. If still not defined by the end of the compilation-unit, that's a style-warning. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Every country has an army, either its own or a foreign one. ------------------------------------------------------------------------------ Everyone hates slow websites.
