To use alternative 1, you need ~lineseq in your eval:

 (eval `(def ~(symbol varname) ~lineseq))


If you don't unquote lineseq like this, then you are def'ing "cards" to the
*symbol* lineseq.  When you later access "cards", it is evaluated to
returns the symbol lineseq.  But since lineseq was a local, it is no longer
in scope.  What you actually wanted was to def "cards" to the value of
lineseq (which is what the unquote ~ does).
