OK, here's another one: if you use 'list(...)' on a vector, does it apply to the vector itself or its members?
You might be wanting to convert a vector into a list:
['one', 'two', 'three']
or convert each of its members onto lists:
Vector([['one'], ['two'], ['three']])
More likely you mean:
>>> [list(i) for i in ['one', 'two', 'three']]
[['o', 'n', 'e'], ['t', 'w', 'o'], ['t', 'h', 'r', 'e', 'e']]
The problem, of course, is that list() now has to understand Vector specially, and so does any function you think of applying to it. Operators are easier (even those like [1:]) because Vector can make its own definition of each through (a finite set of) dunder methods. To make a Vector accept an arbitrarily-named method call like my_strings.upper() to mean:
>>> [i.upper() for i in ['one', 'two', 'three']]
['ONE', 'TWO', 'THREE']
is perhaps just about possible by manipulating __getattribute__ to resolve names matching methods on the underlying type to a callable that loops over the content.
