I have been working on and off for a few years on derivative of the XL2 programming language, adding the missing features I need and some other tweaking. I have also been following the development of Nim, in particular the addition of term rewriting macros which I desperately need to avoid the complexity of expression templates in C++. I am now convinced that Nim has a brighter future than Xl2 and I am planning to migrate.
However, I think that there are many good ideas in the XL2 language and many many similarities to Nim so I thought I would bring it to your attention in case there is something here which is of general interest:

Welcome to Nim! :-)
Indeed I'm aware of XL's design; I even looked at its implementation in detail (meh, interface vs implementation files... ;-) ) but your links are full of interesting stuff that should inspire us.
