Fair use for source code should include:

- writing a book with example code taken from open source projects in
order to highlight good or poor programming technique

- gathering together open-sourced implementations of algorithms in order
to compare them against each other and asses their merits

In general, any "meta-use" of a portion of the source code should be
acceptable, that is, any re-use of a portion of the code whose purpose
is to provide commentary or insight into the original and not replace
the use or function of the original.
