Given the following bit of python setup code:

db = metakit.storage("mkdelete.mk",1)
mainView = db.getas("program[key:S,val1:I,val2:I]")
aView = mainView.select(key='aaa')
</code>
what is the 'right' way to delete the records in aView
from mainView (in python)?
Banging my head on the desk on this....
I think this is the way:
indices = mainView.indices(aView)
mainView.remove(indices)
Here is a test script I just typed into the interpreter
>>> import metakit
>>> st = metakit.storage()
>>> view = st.getas("test[a,b:I]")
>>> for num, s in enumerate("abcdefg"):
... view.append((s, num))
...
>>> s = view.select(a='a')
>>> indices = view.indices(s)
>>> view.remove(indices)
>>> metakit.dump(view)

b 1
