What I do miss sometimes is the ability to inject the contents of a
dictionary into locals.  For example, when I get the results of a
database query in a list of dictionaries or named tuples, I would like
to do something like

for <locals> in sql('select name, age from students'):
     print(name, age)

I can achieve that with hacks like

for x in sql('select name, age from students'):
     locals().update(*x)
     print(name, age)

but I don't think this is guaranteed to work and it is ugly and inefficient.
