Exactly. (Though I prefer library() over requires() here.)
We worked diligently to make this as trivial and reliable as possible.
A connection object is established _once_ when the package is loaded if and
only options("blpAutoConnect") is set to true. Then blpConnect() is called,
and it too relies on options() to get the hostname (if "localhost") and/or
the default port will not do. Once you have that connection, it will be
supplied to all accessor functions -- no need to carry it around explicitly
from call to call.
All that should "just work" as it does for us. If it doesn't for you, please
file an issue at the GitHub repo.
