[elephant-devel] get-instance-by-value where value is a list

[Frank Schorr]

get-instance-by-value returns nil to me in the example below.

May be it is due to my configuration, which is  ele 0.9 on lispworks/win32 with postmodern.

printing the list to a string and storing the string and reading back is ok, however.
