Interesting.  It seems to be a bit more capable around the edges than 
unpack, and certainly has a friendlier looking syntax, but I wonder how 
the performance compares to unpack, for the cases they both handle?  
Seems like for cases they both handle, it could be beneficial to compile 
to the equivalent unpack for speed?

Containers look nice, but it seems it would be nice to allow multiple 
targets: Containers, dicts (with a special entry giving the order of the 
fields, perhaps, for reconstruction; maybe that is what a container is, 
already?), namedtuples, all seem to be reasonable alternative targets, 
with different usage tradeoffs, of course.
