The important safety tip here is that general-purpose pass by construction
is not yet available, and is not on the schedule for v1.0 of E. I haven't
run into any computing problems that I absolutely had to have it for;
currently, if I need to run a block of code on a remote machine, I just have
the software send/receive source for the constructor, and interpret the
constructor to create a new object.
