Bug in 1.8? - subrule Argument passing

The following will successfully pass  arguments to the constraint subrule:

constraint[1, 2, 3],
constraint[1, 2, 3](s) and
constraint[1, 2, 3](s?)

However the one below will NOT

constraint[1, 2, 3](s? /,/)

Is this a known bug, am I doing something wrong or have I made a discovery?
