One of several problems of having a creative commons (CC) license for code generated on Code Review, is that it is incompatible with major software licenses. Your project would have to either have to be re-licensed to, or already use a license compatible with CC to use Code Review contributions. If the licensing could be changed to a more permissive license, say MIT, it would be much easier to integrate code from Code Review into existing projects.
Therefore, I suggest (request) that the license of code in Code Review contributions be changed to MIT.
From creativecommons.org (emphasis mine):
Unlike software-specific licenses, CC licenses do not contain specific terms about the distribution of source code, which is often important to ensuring the free reuse and modifiability of software. Many software licenses also address patent rights, which are important to software but may not be applicable to other copyrightable works. Additionally, our licenses are currently not compatible with the major software licenses, so it would be difficult to integrate CC-licensed work with other free software. Existing software licenses were designed specifically for use with software and offer a similar set of rights to the Creative Commons licenses.
