The PID provider and USDT do not give you nice syntactic sugar for handling user-land data. In DTrace probe context all you can do is copyin and interpret as necessary. It's annoying. In theory the D compiler could generate the necessary DOF code by consuming CTF/DWARF/STABS from the relevant user-land programs and objects; in practice that's a very difficult thing to pull off (this is the standard answer, and I believe it).
