[Python-ideas] Quick idea: defining variables from functions that take the variable name

I agree, I saw this after I posted. If the keyword is 'define' the names
should definitely come before 'as'.

If the keyword is 'expose' as I first thought of, the names should come
after 'as'. Other possible words with names after 'as': reveal, publish,
reify, create, etc. If some word is intuitive enough, I'd prefer this
order. It's closer to what 'import' and 'with' do in conjunction with 'as'.
