Compilation Failed

I will publish that code soon, so it will be possible to try it.

This is the best reproducer I have so far:

git clone https://github.com/stanch/unzimm
cd unzimm
sbt amm
@ def f(a: sourcecode.Text[Zipper[Tree]]) = a.source
defined function f
@ f(Zipper(simpleTree))
Main.scala:330: exception during macro expansion: 
java.lang.UnsupportedOperationException: Position.point on NoPosition
<BAM>

Seems to be fixed by ef7642f
