i just released apipkg-1.0, an around 100 LOC module for easy importing

How about doing something like
host.name=%HOSTNAME%
Then when you parse in the value %HOSTNAME% from your configParser module you

Is there a way to extract code out of a generator function f() into
g() and be able to have f() yield g()'s result without this idiom?:
for g_result in g():
yield g_result
It feels like a clumsy hindrance to refactoring, to have to introduce
a local variable and a loop.
