Nimrod: A New Systems Programming Language

Stroustrup started C++ that way, Walter Bright started D that way, Alan Kay was a strong director for Smalltalk, John McCarthy wrote Lisp,
Yukihiro Matsumoto wrote Ruby, Guido van Rossom wrote Python, to name just a few.

That's really not a good reason to avoid a language, most of the best languages started that way.

About metaprogramming... How can it be detected that there is AST usage when I read sources? May be there is a need in some mark symbol for such functions...operators? PS: I like nimrod as a language and how it is designed. Producing a C or C++ is a greate future. And it's source base is quite small to overvew

The only problem I see is that's a one man project.

It's really a function of what you're used to. You grew up with curly braces, so spaces are odd to you. But for those accustomed to indentation-based syntax, it is no less clear than braces.

Has anyone heard of the "Tower of Babel?"

As far as I'm concerned, any programming language that uses indentation instead of some sort of delimiter (brackets) to delimit a scope of control is just brain dead! That's why I don't use python and such. I want it to be CLEAR where my control blocks are, and not to need to guess...
