Au contraire.  It is so natural than even suits use nested indentation
to show hierarchy in their PowerPoints.

The difficulties arise when things *aren't* just represented
hierarchically, when people start to want shortcuts that are more
compact than pure hierarchy.  The great advantage of classical Lisp
indentation is that it saves vertical whitespace.  Attempts to reproduce
this virtue within the different context of indentation are where the
epicycles come in.
