Scala 3 macro, function invocation problem

Question
1

Hello folks, I am working on macro that call a method / function. I was able to do an implementation, but I am not happy from way how it is working. My implementation look like :

inline def getSql[T](methodName:String)(using ctx: SqlContext): Sql =
  ${ getSqlImpl[T]('ctx, 'methodName) }

private def getSqlImpl[T: Type](ctx: Expr[SqlContext], methodNameExpr:Expr[String])(using Quotes): Expr[Sql] = {
....

and invocation looks like :

override def sql: Sql = getSql[TestSelect]("s")

so I must pass the name of the method, in this case “s” and also class (TestSelect) where method is applied.

I am looking for better solution, I switched from methods to functions, for example:

private[sql] val s =  {(name: String, age: Int) => sql"select * ${from[User]} where name = $name and age = $age"}

is function I want to call.
I am struggling with invocation of the function.
Here is almost whole implementation, I skipped only args retrieval:

inline def getSql[T](method: T)(ctx: SqlContext): Sql =
  ${ getSqlImpl('method, 'ctx) }

private def getSqlImpl[T: Type](m: Expr[T], ctx: Expr[SqlContext])(using Quotes): Expr[Sql] = {
  import quotes.reflect.*
  val functionClass = TypeRepr.of[T]
  // Find the sqlStatement method
  val method = functionClass.typeSymbol.methodMember("apply").headOption.getOrElse {
    report.errorAndAbort(s"Method apply not found in class ${functionClass.show}")
  }
  // Get parameter names and types
  val paramSymbols = ???  // skipped code

  val result = Apply(Select(This(functionClass.typeSymbol), method), args.toList)
  result.asExprOf[Sql] // <-- ERROR 
}

error is :

[error]    |  Expected type: com.birl.sql.Sql
[error]    |  Actual type: Function2.this.R
[error]    |  Expression: Function2.this.apply(ctx.params.getOrElse[scala.Any]("v

I am not sure what I am doing wrong, but is clear, that function is not invoked.
Thanks for help.
