- What items do you unconciously look for as signals that what you're reading merits a closer look?
Firstly and most commonly: poor function names. Secondly and almost as common: poor variable names. Thirdly: poorly written comments.
If I see @n[$i] I get very worried.
- Are there items that make you feel more comfortable with the code?
Good function names, variable names, and comments.
- Do you feel you can rate the experience level of the author by how the code looks, both in Perl and programming in general?
Generally and to some extent, yes. But there are lots of exceptions. There are some capable but entirely self-taught developers who have peculiar styles and I've seen some really lousy Perl code written by very good C programmers. At the extreme lower end of the scale, though, it's usually easy to judge experience, at least with a particular language.
- Has your style changed as you have improved as a programmer, both in Perl and in general? If so, how?
Sure. How? That's a big question. I guess a concise way to put it is that my code has gotten more expressive. By which I mean that my intentions are, I think, more transparent to the reader. Another shorter way to put it is that my code makes more sense these days... ;-)
- Do you think that the style of a piece of code can contribute to its maintainability?
