Sounds like Julia to me :p
"..We want the speed of C with the dynamism of Ruby. We want a language that’s homoiconic, with true macros like Lisp, but with obvious, familiar mathematical notation like Matlab. We want something as usable for general programming as Python, as easy for statistics as R, as natural for string processing as Perl, as powerful for linear algebra as Matlab, as good at gluing programs together as the shell."
Looks like it has the kind of macro system I'm talking about. I don't know how I feel about the language as a whole, but I'm glad people are exploring in this direction.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
