I'd like to use some code in the example implementation section of a C++ standard committee proposal. (Specifically, from A Proposal to Add Y Combinator to the Standard Library.)
The paper itself is publically available but what is the license of the code contained therein?
(I am under the impression that this question would be off topic at SO. But on this stack it is very hard to find a tag that fits the question, except the obvious one. Maybe that will change over time.)
