I am curious about the usefulness of sqlite's "unique" type handling, and
so would like to know if anyone has ever actually found any practical use
for it/used it in some project? I am referring to the typeless handling,
e.g. storing strings in integer columns etc., not to the non-truncating
system

SQLite is not unique in this respect. Lots of other languages use
flexible, dynamic typing: Javascript, Perl, Python, Tcl, AWK come quickly
to mind. SQLite began as

I use it in a pro
I program mostly on Perl on Linux and it is a beautiful fit. Example
is I can have a date field with a POSIX time value (or offset) in it
or another date related value like "unknown"

Yes, This feature is very useful for storing hierarchical data - XML,
JSON, ASTs, objects in the script engines (e.g. Lua, Python, ...), etc.

Really ? I don't know about ASTs, but aren't XML and JSON encodings just
strings ? You could encode anyt

I am using this feature a lot. My applications log all changes to the
database, SQL and parameters. So I have an attached log.db with a field for
the SQL and then 32 typeless columns for the parameters. Works like a charm!

Sqlite's dynamic typing made it a natural fit for using it with Python
UDFs in madIS:

Absence of the feature would have complicated the whole "functional
relational" [*] workflow that madIS uses a *lot*.

[*] Instead of Python functions calling SQL, have S
My thoughts follow:
Be lenient in what you accept; be stringent in what you produce.
I believe SQLite follows this principle.

No. And I guess I wouldn't need it. If I need that in other systems, I
simply use the most generic type, varchar/text or blob. This way, at
least it's obvious that text can
