False positive warning about passing implicits with a using clause in 3.7 nightly

[mrdziuban]

Compiler version

3.7.0-RC1-bin-20250304-bef520f-NIGHTLY

Minimized code

//> using dep org.scalikejdbc::scalikejdbc:4.3.2

import scalikejdbc.*

given sess: DBSession = NoSession

def one = SQL("SELECT 1 AS x").map(_.get[Int]("x")).single()

Output

-- Warning: --------------------------------------------------------------------
1 |def one = SQL("SELECT 1 AS x").map(_.get[Int]("x")).single()
  |                                                            ^
  |Implicit parameters should be provided with a `using` clause.
  |To disable the warning, please use the following option:
  |  "-Wconf:msg=Implicit parameters should be provided with a `using` clause:s"

Expectation

There should be no warning -- def single returns an instance of SQLToOption[A, E], which inherits def apply() from SQLToResult.

The () are required to properly call apply(). I tried changing the code to

def one = SQL("SELECT 1 AS x").map(_.get[Int]("x")).single.apply()

but it yields the same warning. And remove () yields an error:

def one = SQL("SELECT 1 AS x").map(_.get[Int]("x")).single.apply
-- [E100] Syntax Error: --------------------------------------------------------
1 |def one = SQL("SELECT 1 AS x").map(_.get[Int]("x")).single.apply
  |          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  |         method apply in trait SQLToResult must be called with () argument

Thanks for the excellent links. I'm guessing

#22567

because https://github.com/scalikejdbc/scalikejdbc/blob/4.3.2/scalikejdbc-core/src/main/scala/scalikejdbc/SQL.scala#L1095

shows implicit with default args.

Assuming it's a duplicate of #22567, let's track it there.
Feel free to reopen if they turn out to be separate.
