Even though you can do `@which naked_function` it's a fair position to have that you prefer to import modules and be explicit about where they come from. I tend to prefer explicitness like that in package code, but for data analytical scripts (like the examples here) it would be superfluous in my opinion.

It is nice that Julia leaves this style decision to the user. I personally find the constant prepending of modules to be one of the clumsiest aspects of Python for data analysis.
