Yes, actually my second option was to look at the real debugger. It seems that GPS is nicely equipped with gdb interface and after adding the debug and symbol flags to the compilation, I can step on the debugger and hover with mouse cursor on the record instance to see the components and values. Very nice!

That would be cool, but honestly, after using the debugger, the prints are just too much to bother with. :) Perhaps in plain text console environment that would play it's part, but now I think I'll just go with the debugger.
