I have path length using a path variable and a pathLength() function. It 
counts the number of edges in the path:

?x exp :: $path ?y
filter(pathLength($path) <= 10)

I would also support handling length in the path expression.

I don't understand "does it matter" in the question.
It may happen that there are paths with less steps and path with more, 
but if there are steps between N and M it should be ok ?
