- BoundMethodHandle

  57         assert(speciesData() == speciesData(form));

I am missing some context here as to how that assert would pass for anything 
other than Species_L, namely for sub-classes of BoundMethodHandle generated by 
generateConcreteBMHClass how does that assert return true?


 153     public static SpeciesData speciesData(LambdaForm form) {

Minor point. Could be private (since only used by the assert in the 
constructor), or package private if the intention is for it to be used by other 
j.l.i classes in the future.
