So you mean: Eclipse defines &DB::sub, but neglects to define: "$_Unique"?

It seems so. Eclipse has no idea of what Win32::OLE does, and it definitively should not mess with the internals of Win32::OLE. It's worse enough that Eclipse messes with perl at all. It uses some debugger hooks, one of them is &DB::sub (documented in perldebguts). One could discuss if it should do so, but it makes some sense if you want to single-step a perl program from within Eclipse. Win32::OLE also uses debugger hooks. But Win32::OLE is no debugger, not even remotely. It does so because there seems to be no other way to get some information. This is not nice, and the only way to prevent this collision is seems to be to use either Eclipse or Win32::OLE, but not both. You can still write perl code in Eclipse, but use a clean perl from outside Eclipse to run your code. On Windows, a double click on the *.pl file may be sufficient, else open a command prompt and type perl yourscript.pl.
