Review Comment:
> instead of doing another round of PR reviews I figured I would just push
the commits directly to save time.
Thank you! I’m just curious—is storing a parquet file in slt tests common?
The tests I’ve worked with so far use tables created in the same test file.
> Strangely they don't seem to care about errors:
Interesting! This makes me wonder if they treat this behavior as an
"optimization" or if it's simply an expected behavior to cast the literal to
the column's type.
> I played around a little locally and this is what I came up with. What do
you think?
Oh, this looks much better! However, I’d prefer leaving the outer match as
is, maybe there’s potential for another optimization in the future?
