XML is not a programming language. It's a platform for flexible AST
development. It's meant to be tools-driven. Perhaps the tool support
on the authoring side has not been realized as well as it should have
in terms of XML build and config files. But certainly we get to enjoy

Some usage of XML just seems to model an AST and as such, are indeed

The risk, of course, is to choose a framework in your chosen language
because you can stay in your comfort zone. The framework is implemented in
Java, you know Java,
I think the emphasis should not be to "learn a new language" but
"don't stop learning".
It doesn't have to be a language specifically, the thing is to not sit
inside your comfort zone all the time - not least because the world

There is no right or wrong topic in my opinion. Just whether you are still

Well, the moment a class or interface is publicized - they are
effectively immutable, especially in Java, where virtual-by-default
can easily cause a newly introduced method in a base class clash with
an unknowing derived class, resulting in ClassLoader exception. You
