Hi everyone,
in Elixir we work a lot with maps (or at least I do :D). And we know and
love Map.merge. However given a map like %{a: %{b: 1}} and we want to
merge it with a map like %{a: %{c: 2}} then the :a key will be totally
overridden with whatever is supplied in the other map.
However, for instance for configuration, what we might want is the
result to be %{a: %{b: 1, c: 2}} - e.g. if the value is a map on both
sides recursively merge that as well.
It is rather simple to implement in elixir with Map.merge/3 [1] but I
think it'd still be helpful to have it in elixir core (otherwise I'll
make a mini hex package :D). E.g. it is useful and it'll keep people
from wondering about it or writing their own a little flawed
implementations.
So, what do you think - Map.deep_merge in elixir-core - yay/nay? I'm
happy to draft a PR if it gets the sign of approval.
