Rather than define a bunch of `__field__/1` functions on the caller module as the `field/3` macro is invoked, we only collect field definition metadata in an accumulator attribute. Later, we serialize the field definitions together into a formatted map on demand via `__schema__(:fields)`. This change will allow users to define fields on their schemas in for comprehensions or maps, without any compiler warnings about unmatchable function heads.
