It's not there.

Yes, we have a system (see tools/litre) that allows us to embed
testing instructions in the source for our documentation.  Actually
the process assembles source files and a Jamfile.  We then run all the
tests in that Jamfile.  If you look at the .rst files that document
the use of lambda, you can see that those examples are tested.

Daniel, can you do that?
