Rant after trying Rust a bit

[Alex Parrill via Digitalmars-d]

I'm not at all familiar with Rust, so forgive me if I'm 
misinterpreting something.

I think I read that this may happen soon.

You can make a `conformsToSomeInterface!T` template, and use 
`static assert`. D ranges, and the upcoming std.allocator, 
already use this sort of 'interfaces without polymorphism'.

Ex. `static assert(isInputRange!(MyCoolRange));`

Most of what macros in C were used for are now done with 
templates, static if, etc. (I don't know how Rust's macros work). 
Tools could theoretically execute `mixin`, but it effectively 
requires a D interpreter. A library to do that would be really 
nice.

Look into `std.typecons.Unique`, though I've seen people posting 
that they don't like it (I haven't used it much; I had one use 
case for it, which was sending it through `std.concurrency.send`, 
but it doesn't work with that function).


Yes, D's community is pretty small. It's not something you can 
just code; you have to market the language. And it's the 
community that creates the many tools and packages.
