| Yup, using "you" in headlines is a pattern that needs to die.

| I get that it's attention-grabbing, but it's because it's rude.
|
| You don't know anything about me. You don't know what I think
| or what I already know or what I won't believe.
|
| I know it's not a big deal in the grand scheme of things, but

| right" and not even click on it.
|
| That said, it does annoy me too.
|
| Also what annoys me is that I constantly try to play devils

| the conclusion of the advocate.

| Reasons to use dataclass(slots=True) instead of TypedDict
|
| - Faster attribute access: your code is faster
|
| - Slotted classes take less RAM, less L1 cache pressure, your
| code is faster
|
| - Wrist friendly to with .foobar instead of ["foobar"]
|
| - Runtime error if you misspell an attribute name

| It's Python. Does L1 matter at all? I assume anything you're
| accessing is behind a few pointers and __dict__ accesses
| anyway.
|
| For me it's mostly about .attribute being more in line with the
| rest of the language. Kwargs aside, I find overuse of dicts to
| clunky in Python

| Whether or not the performance matters...well that's somewhat
| subjective since Python has a fairly high performance floor
| which makes performance concerns a bit of a, "Why are you
| doing it in Python?" question rather than a, "How do I do
| this faster in Python?" most of the time. That said it _is_
| more memory efficient and faster on attribute lookup.

| Anecdotally, I have used Slotted Objects to buy performance
| headroom before to delay/postpone a component rewrite.
