I thought the same some time ago, but was able to leave the
dark side behind me and become a good jedi.

# You'll have headers that depend on other headers, but without that
# relationship being expressed in the source.

This is exactly what I want to avoid. I *want* the dependencies to be as
clear as possible. I want to look at the include directives and have
them stare right at me; it helps me realize when there is too much
interdependency emerging and rethink modularization and write smaller
sexier interfaces.

Sprinkling yet another include in yet another header is just piling mess
upon mess.
