Slightly more on my initial behavior:
TypeError: Ambiguity vectorizing a map, perhaps try it.keys(), it.values(), or it.items()
TypeError: Vector can only be initialized with an iterable
<Vector of 'hello'>
I'm wondering if maybe making a vector out of a scalar should simply be a length-one vector. What do you think?
Also, should a single string be treated like a vector of characters or like a scalar? It feels kinda pointless to make a vector of characters since I cannot think of anything it would do better than a plain string already does (largely just the same thing slower).

Here is a very toy proof-of-concept:
from vector import Vector l = "Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec".split() v = Vector(l) v
<Vector of ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']>
<Vector of ['jXn', 'feb', 'mXr', 'Xpr', 'mXy', 'jun', 'jul', 'Xug', 'sep', 'oct', 'nov', 'dec']>
vt = Vector(tuple(l)) vt
<Vector of ('Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec')>
<Vector of ('jan', 'feb', 'mar', 'apr', 'may', 'jun', 'jul', 'aug', 'sep', 'Xct', 'nXv', 'dec')>

One thing I think I'd like to be different is to have some way of accessing EITHER the collection being held OR each element. So now I just get:
<Vector of [3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3]>
Yes, that's an ugly spelling of `len(v)`, but let's bracket that for the moment. It would be nice also to be able to ask "what's the length of the vector, in a non-vectorized way" (i.e. 12 in this case). Maybe some naming convention like:
This last is just a possible behavior, not in the code I just uploaded.

is a lot nicer than:
[s.title() for s in (s.lower() for s in [s.strip(s) for s in
list(map(str.title, (map(str.lower, (map(str.strip,
a_list_of_strings)))) # untested
In this case you can write
[s.strip().lower().title() for s in a_list_of_strings]
What if it's a more complicated example?
where the len() is supposed to give back a list of the lengths of the first hundred strings, sorted case insensitively? (Okay so it's a horrible contrived example. Bear with me.)
With current syntax, this would need multiple map calls or comprehensions:
[len(s) for s in sorted(s.casefold() for s in a_list_of_strings)[:100]]
(Better examples welcomed.)
