Here's a good function header given the following:
I wrote the below code

    def encode_addr(addr):
        (name, email) = addr
        if (not try_coerce_ascii(name)):
            name = str(Header(name, 'utf-8'))
        return formataddr((name, email))
    addresses = getaddresses([ustr(header_text).encode('utf-8')])
    return COMMASPACE.join(map(encode_addr, addresses))

What's a good function header?
