FullName does not work in for loops

import $ivy.$                              

@ def loop = {
    for (i <- 0 until 1) {
      println(implicitly[sourcecode.FullName])
    }
  } 
defined function loop

@ loop 
FullName(ammonite.$sess.cmd1.$anonfun)

The loop function should be present in FullName. Unfortunately it is not.

I noticed related but probably different misbehavior.

@ def test(): Unit = {
        for {
          _ <- Option(())
          _ <- {
            println(implicitly[sourcecode.FullName])
            Option(())
          }
        } ()
      }
defined function test

@ test
FullName(ammonite.$sess.cmd2)

It starts to work if the initial step is removed:

@     def test2(): Unit = {
        for {
          _ <- {
            println(implicitly[sourcecode.FullName])
            Option(())
          }
        } ()
      }
defined function test2

@ test2
FullName(ammonite.$sess.cmd4.test2)
