Abstract

We present F(Eml), a language that combines classes, extensible functions, symmetric multiple dispatching, and a practical system for parameterized modules. Parameterized modules permit subclasses and function extensions to be defined and typechecked once, and then reused to extend multiple argument modules. F(Eml)’s predecessor, Eml, supported classes and extensible functions with multiple dispatch, but its support for parameterized modules was weak. F(Eml)’s key novel features are alias declarations, generalized type relations in module signatures, and a nontrivial definition of signature subsumption.

Keywords

Parameterized Module Abstract Class Argument Type Extension Type Deduction Rule 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
