I mostly agree, but I had trouble with today's puzzle. It's a recurring problem of mine: if the input is not specified completely, I have trouble figuring out what it is, even when I study it, so I often get subtle bugs. And there's a LOT of input. In my input, a turn of 270 degrees doesn't show up until line 85, so I didn't see it even after scanning the file (which I did because I wanted to make sure it had integer-only positions and the turns were multiples of 90). Once I figured that out, it was quite easy.
I guess the moral of the story is that I need to think more carefully about what come through the input, as well as rely more on validating that the input meets my expectations.
