[armedbear-devel] Package redefinition issue in REPL.

Hello dear developers, I' just experienced an odd issue with defpackage. It looked like the package will not be modified if I call defpackage again. For example, I define a package called "a-package". After a while I wanted to export a function that I've just implemented called "a-new-foo". Naturally I would add a new entry under the :export section of defpackage, and then eval the expression again. However, I still cannot access "a-new-foo" as the REPL gives me "such symbol is not external of package [a-package]" error message. Please advice and many thanks, Wei-Lun Chiu
