Convert FList to List and Set

GoogleCodeExporter commented 8 years ago

import groovypp.concurrent.FList

FList<String> l = FList.emptyList.addAll(['2'])
println(l as List)
println(l as Set)

now fails at runtime:

org.codehaus.groovy.syntax.RuntimeParserException: The return type of 
groovypp.concurrent.FList remove(java.lang.Object) in 
FList$OneElementList_delegateProxy is incompatible with boolean 
remove(java.lang.Object) in java.util.List

IMO FList should implement List, then it will become compatible with tons of 
existing code. And the similar thing with FHashMap
