	Next, in a lisp-listener, I evaluate the following:

	(export 'jfoo "jtest")
	;;;here I got a complaint that the symbol JFOO is not present in package JTEST
	;;;this I understand
	Back to Dribbling Lisp Listener in Dynamic Lisp Listener 2.

	(export 'jtest:jfoo "jtest")
	;;;here I got a complaint that exporting the symbol JFOO would cause a name
	;;;conflict in USER- this I don't understand <****************************

    When you typed the previous form you created USER::JTEST.  Since USER
    :USEs JTEST, exporting FOO from JTEST would cause a conflict.

	;;;Finally, I tried importing JTEST:JFOO into USER but it complained that
	;;;"this would cause a name conflict with JFOO which is already present"
	;;;This I dont understand <***********************************

    This is the same problem as the previous one.  When you typed 'JFOO in
    the first EXPORT form, you interned a symbol named JFOO in USER.

I believe the symbol 'jfoo got interned in the lisp-listener's package
when the form "(jfoo)" was typed in.
