Following snippet doesn't match even though it should:

val q"""
  var $$tmpscope: _root_.scala.xml.NamespaceBinding = $$scope
  $$tmpscope = new _root_.scala.xml.NamespaceBinding($prefix, $uri, $$tmpscope)
  {
    val $$scope: _root_.scala.xml.NamespaceBinding = $$tmpscope
    ..$last
  }
""" = q"""<foo xmlns="bar"/>"""

Workaround:

val q"""
 var $$tmpscope: _root_.scala.xml.NamespaceBinding = $$scope
 $$tmpscope = new _root_.scala.xml.NamespaceBinding($prefix, $uri, $$tmpscope)
 ${build.SyntacticBlock(q"val $$scope: _root_.scala.xml.NamespaceBinding = $$tmpscope":: last)}
""" = q"""<foo xmlns="bar"/>"""

@densh said:
Actually the problem here is lack of line between assignment and the block that follows it. So instead of having a 3 statement block you get 2 statements. This is not a bug.
