Could it be a blessed object or something else?

I think the AM post is onto something, Devel::Peek shows that $CFG{target} has some magic of type PERL_MAGIC_uvar attached to it. Not being a Tk expert I can only guess that the magic is probably necessary to bind the value to the widget, but the fact that this causes $CFG{target} =~ ... to behave differently than usual smells like a bug to me. But if the app needs to work on a range of Tk versions, it looks like the workaround might be necessary.
