The following passage is particularly unsettling.

"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."
