You can't alias a type to this. You need to instantiate it
first, then alias the instance to this (because 'this' is an
object, not a type). For example:

I feel like i need to fully re-learn and familiarize myself with
D now.
This is an interesting error I'm coming across, it's not
pointing to anything in particular. I've used the -v verbose flag
and it seems to appear each time after a struct declaration.

"How easy is it to convert both C++ programs and C++
programmers to D?"
Porting C code to D is not hard, it's mostly mechanical work, you
just have to keep an eye on few things (like passing fixed-sized
arrays to functions by reference, global floating point data not
initialize
Thanks for your reply!

We work in the embedded linux real time area,
I think you could use D for embedded area, but I think of D more
like a low level application language.

dmd is more updated and it's the reference one, it compiles fast,
but it produces

is tried to get used. You can't use whole phobos (yet) without gc.

So, time to get serious and sit down and learn it.

Hello all,
I came across an interesting little pitfall of delegates recently which I

TL;DR: having reference types as struct members can be dangerous. ;-)
Suppose we have a fairly simple range which is supposed to count from 0 to some
maximum. The trick is that the count

I don't think the format is sufficient for recreating the array:

Bah, what would be the meaning of accepting the shebang syntax
then? SCripts are made to provide a quick way to hack: you edit
it for 5 mins, you run it. You change a parameter inside, you run
it. Otherwise, there would be no need for scripts, everything
could be compiled, even if you fill ever
