We have made an implementation of the language Lambda-H, described in the
paper Hybrid Type Checking by Cormac Flanagan, which uses a hybrid type
checking system. We have tried to keep our implementation as close as possible
to the language defined in Flanagan's paper. The result should be seen as a
proof-of-concept, and an exercise in implementing a hybrid type checker for a
language with advanced type specifications.
At one point, Open Hub analyzed source code for this project based on code location(s) available at that time. Since then, the code locations have been removed.
