Doug Hoyte, "Let Over Lambda-- 50 Years of Lisp" (2008): "It must also be pointed out that aif and alambda, like all anaphoric macros, violate lexical transparency. A fashionable way of saying this is currently to say that they are unhygienic macros. That is, like a good number of macros in this book, they invisibly introduce lexical bindings and thus cannot be created with macro systems that strictly enforce hygiene. Even the vast majority of Scheme systems, the platform that has experimented the most with hygiene, provide unhygienic defmacro-style macros-presumably because not even Scheme implementors take hygiene very seriously. Like training wheels on a bicycle, hygiene systems are for the most part toys that should be discarded after even a modest level of skill has been acquired."
