Hi,
Would it make sense introducing a trailing bang version mirroring the
existing Map.take/2? It would behave the same but fail with a KeyError on a
missing key instead of simply ignoring it.
To give some context, I've lately found myself writing things like `%{foo:
data.foo, bar: data.bar, ...}` quite frequently, a typical use case being
to dump only some fields from a map or struct into a JSON payload or
Elasticsearch. While it's tempting to refactor those using `Map.take/2`, it
feels best to fail frankly than omitting fields accidentally in order to
avoid potential bugs.
I suppose we would also introduce Keyword.take!/2 for consistency if we
move forward.
What do you think?
Cheers,
Sabiwara
