REPL Classes cannot have noargs constructors #2

Closed kmader closed 8 years ago

kmader commented 8 years ago

Since the classes are compiled as subclasses they are forced to have a first argument and cannot be initiated with an empty list <init>()

Detailed error below, information in Create Ops notebook
