Setting the context of one fn's functionality to be another fn turned
out to be slightly complicated, since an fn by default sets the
functionality's context to himself, not the value of his this keyword
— as such, using 'call' or 'apply' does not work.  I came up with a
number of alternative solutions in functional_node-invocation_styles.js.

Before that, I changed indentation style in universal.js yet again,
and made an abortive attempt at implementing the last vision in
namespaces_and_other_values.js.
