One of my favorite interview questions is "What is your favorite programming language and what would you change about it if you could?" Any answer along the lines of "I wouldn't really change anything." shows a lack of either experience or willingness to think about your tools.

Or it could be a sign of pragmatism, or having the freedom to choose your tools.

Why wish your tool changed instead of focusing on using it, or something better suited, to produce things?

[Tainnor]

Because every tool has limitations, and even if you think your tool can't/shouldn't necessarily be changed you still need to be aware of its gotchas to use it effectively.
