Question: Why is _queries in QueryCollection private?

[realjanpaulus]

I would like to execute all queries of my QueryCollection like in the following example:

create_queries = QueryCollection.from_file("src/queries/create.sql")
for _, query in create_queries._queries.items():
    db.execute(query)

Does _queries has to be private? If not, one could access it directly (although it is obviously also now possible to do this, but not recommend because it is private 😉 ) and looping over it.
Alternatively, one could add the following getter function:

def get_queries(self):
    return self._queries

Good point. I'd suggest to make QueryCollection inherit from collections.abc.Mapping that you can do something like:

queries = QueryCollection.from_file("queries.sql")
for key, query in queries.items():
    db.execute(query)
