Looks interesting, but how does it compare
to https://hex.pm/packages/short_maps as it adds a sigil that does
something similar?
```elixir
import ShortMaps
my_map = %{foo: 1, bar: 2, baz: 3}
~m(foo bar baz)a = my_map
foo #=> 1
import ShortMaps
name = "Meg"
# String keys by default (or with the 's' modifier)~m(name) #=> %{"name" =>
"Meg"}# Atom keys with the 'a' modifier~m(name)a #=> %{name: "Meg"}
iex(1)> import ShortMapsnil
iex(2)> name = "Meg""Meg"
iex(3)> ~m(^name)a = %{name: "Meg"}
%{name: "Meg"}
iex(4)> ~m(^name)a = %{name: "Megan"}** (MatchError) no match of right hand
side value: %{name: "Megan"}
```
And other stuff
