Issue with parameters in relation to in and a dynamic/1 collection

[LostKobrakai]

Doesn't work:

val = dynamic(^["abc", "def"])
cond = dynamic([a], a.col in ^val)
query = from a in "table", where: ^cond, select: a.col

{sql, x} = Repo.to_sql(:all, query)
# sql = SELECT t0."col" FROM "table" AS t0 WHERE (t0."col" IN (?,?))
# x = [["abc", "def"]]

Works:

cond = dynamic([a], a.col in ^["abc", "def"])
query = from a in "table", where: ^cond, select: a.col

{sql, x} = Repo.to_sql(:all, query)
# sql = SELECT t0."col" FROM "table" AS t0 WHERE (t0."col" IN (?,?))
# x = ["abc", "def"]

Looks like there's some place flattening out the parameters, which doesn't catch the dynamic case

I'll look into this soon.
