So using reflection on the objects gives the following signatures - they
have identical signatures :
{:name apply,
:return-type com.cra.figaro.language.CompoundDist,
:declaring-class com.cra.figaro.language.Dist$,
:parameter-types
[scala.collection.Seq
com.cra.figaro.language.Name
com.cra.figaro.language.ElementCollection],
:exception-types [],
:flags #{:public}}
{:name apply,
:return-type com.cra.figaro.language.AtomicDist,
:declaring-class com.cra.figaro.language.Dist$,
:parameter-types
[scala.collection.Seq
com.cra.figaro.language.Name
com.cra.figaro.language.ElementCollection],
:exception-types [],
:flags #{:public}}
