Comments in query?

Can I write comments in query, so that only God but also me remember what I was doing?

I just started learning SPARQL, so forgive my ingnorance.

For example:

SELECT ?names
WHERE {
  ?names dbo:award :Turing_Award // get names that won Turing award
}

that throws a parsing error.

A negative answer will also be accepted!

I am using SPARQL endpoint over the DBpedia data set at http://ift.tt/UeVHu1 .
