Sorry for losing my temper about this in my last posts.
In Python they have faced this problem using two different things, str() and repr(), the first one produces a little more readable output, used for normal reading, and then second is a little more for textual serialization (But both use the []).
The shell outputs using repr(), the print uses str(), the items inside collections are always represented with repr().
Objects can define the __repr__ and __str__. Print calls the __str__. If __str__ is missing it's used __repr__.

I like handy defaults, they save time iff they are well chosen.
