   That won't work if Thrust namespaces it, likely they already do. Since in PETSc it is a macro it just goes and replaces itself everywhere and doesn't pay any attention to namespaces or anything. The only way Thrust can help us is to not use VecType :-)

   I agree. I was stupid as a rock in 95 when I didn't stick PETSc in front of everything. Then a few years later I stuck PETSc in front of a few things like Viewer but I should have stuck it in front of everything. Now, will we be smart and stick PETSc in front of everything or remain stupid without it?  Note: we are stuck with the asinine C 31 character limit which means adding the PETSc means messing up shortening some good names we have currently.
