scala> val s = repl.stringToCompilerType("scala.Some")           
s: repl.compiler.Type = object Some

scala> val applyMethod = s.members.find(_.name.toString == "apply").get
applyMethod: repl.compiler.Symbol = method apply

scala> val param00Name = apply.paramss(0)(0).name                      
param00Name: repl.compiler.Name = x
