I worked on my open source projects:
My Erlang implementation as interpreter in C#:
First mailbox tests, including delayed message; adding lists as predefined module; write and test lists:map, lists:filter, lists:any, lists:all, lists:sum.
Parsing fun, with one clause and multiple match clauses.
My Scala-like interpreter in C#
I added binary arithmetic functions, variable expression first implementation (with context to hold the values), val command, object command.

I worked on three non-public projects.
More fun is coming.
