Maybe it's the first serious proposal for D macros I see :-)
Is it possible to re-use the <[ ]> syntax (and $...) for other purposes?
That syntax is just an abstract syntax, it does not need to look like
that. I'm thinking we could do something similar to Scala's reify macro.
I call this the "ast" macro. Look at the header "The AST Macro".
But to answer your question, no. It didn't cross my mind.
Have you seen the macros of Scala language? http://scalamacros.org/
Yes, this proposal is basically the same as macros in Scala, just
adapted the syntax for D.
Regarding the attribute macros, my main use case for them is to extend
the D type system in some ways. How well is such usage supported?
It might be possible, depending on what you want/need. I'm thinking you
can do something like this:
@foo int a;
Which is replaced with:
Foo!(int) a;
It's a different type so depending on how you look at it you could say
it affected the type system.
