Description

Similar to Scala's Dynamic http://www.scala-lang.org/api/current/index.html#scala.Dynamic

We should be able to write builders that are usable from statically compiled code. To achieve this I recommend the following:

// if the object implements methodMissing dispatch to it
foo.bar("blah")      ~~> foo.methodMissing("bar", "blah")
// if the object implements propertyMissing dispatch to it
foo.var1           ~~> foo.propertyMissing("var1")
// if the object implements propertyMissing dispatch to it
foo.var1 = 10      ~~> foo.propertyMissing("var1", 10)

When combined with GROOVY-7956 it would then be possibly to fully implement builders that are compatible with @CompileStatic and certain existing builders could be enhanced to take advantage of this feature JsonBuilder, MarkupBuilder etc.
