In my view they are unrelated: on the one hand "gset" is really an 
interactive feature, where typing is costly so "automagic" might make 
sense; on the other hand "into" is a scripting feature, where you want to 
understand the code and have something as readable as possible, without 
surprises.

The commands are named differently and behave differently.

If someone thinks that "gset" is a good idea for pgbench, which I don't, 
it could be implemented. I think that an "into" feature, like PL/pgSQL & 
ECPG, makes more sense for scripting.
