I worked on a millions of LOC of generally not-that-well-written Delphi code back in the day. Aside from the generally not-amazing quality of the code, it was never hard to debug, nor necessarily maintain.

There are many valid criticisms to levy at Delphi and Python, but those ain't it.

Similar. We have fairly large project, a few MLOC with many hundreds of windows/forms, all kinds of IO and whatnot. We've got code in production that was written back in Delphi 3 days (1997) that's chugging along just fine.

The only thing I think is hard to debug is focus related issues, due to the Windows event loop getting in the way. That's hardly a Delphi-specific issue though.

Other than that debugging and maintenance is quite easy. In fact we don't have to spend much at all on actual maintenance, as backwards compatibility has been great in the new versions. For example, the switch from non-unicode to unicode strings took us just a couple of days. And we're in the Nordics so we'd notice quick with our "weird" letters.

That and losing the source code for some random, obscure vcl component you found on torry's back in the late 90s :-)
