Accessing values in maps, keyword lists, and structs in Elixir

get-values.ex

# Accessing values in maps, keyword lists, and structs

# 1. using . they key can’t be missing, works with structs or maps, but not with keyword lists
# 2. using […] works on maps and keyword lists, but not structs. Key can be missing and i’ll return nil
# 3. Map.get(…) works on maps and structs, but not keyword lists. will return nil if key is missing

If this is wrong then blame @atomkirk 😏
