SleekDB Extension of builtin "named functions" by users

[REDAL]

Hi SleekDB Community,
what do you think of, applying given functions on selected columns,
for example, I need to use hash sha256 on '_id'

could/should be available for "select", "insert" etc.

container->createQueryBuilder()->select(["hashed_id" => hash("sha256", "_id"), "username"])->getQuery()->fetch();

rather than, saving a new column with hashed data, or remapping the array, when returned and adding the hashed values

of course, the idea is to apply, any given declared and existing function within your code, and it's not only for hash, your imagination is the limit

for example, tell sleekdb to hash the column on creating,
or search a column with hash content,

like,
->where(hash("sha256", "userid"), "=", "hash")

WHERE "userid" is a column within the database
