#lisp macros offer the programmer a unique unparalled unheretoforeseen before superpower that is the envy of the users of lesser languages the world over: that of being able royally fuck up code that hasn't even been written yet.
@mousebot ... unless you take FEXPRs like in #PicoLisp - they are better than #Lisp macros because they are normal functions, more readable, and can be debugged (e.g. single-stepped).
