Why can't we allow mixin templates to contain statements, as is the case
for regular mixins?
Is there a workaround?
here's a dummy example:
template mixin Foo{
//some statement, eg: 'return;'
}
void fun(){
mixin Foo;
}
Note that I can do this with a regular mixin, but template mixins are

In case you didn't know, if you're not running the program in visual studio,
you should see the output in in DebugView:

I was wondering what the idiomatic D way of implementing strong
types. Boost has something along these lines using classes:

When programming in C++ I find that the compiler does not
necessarily generate good code with these types,
Hi all,
I am new to D and so far it is really great.
I am wondering how to get the names of member variables in a
struct or class. I haven't worked it out yet but this would
enable metaprogramming like iterating over the members of the
struct.
I see in std.traits that you can get get
You can do it this way:
struct dollars_t {
uint _dollar;
this(uint d) {
_dollar = d;
}
alias _dollar this;
}
struct cents_t {
uint _cent;
this(uint c) {
_cent = c;

alias _cent this;

Interesting. I think in the second example there are pathological

Hi, I have a question about how the GC handles this case:
export extern(C) char* foo(){
char[] x = This is a dynamic D string..dup;
return(cast(char*)x);
}
Since x is pointer to array data length if it goes out of scope,
it's destroyed and the last reference to the array data is gone.

Returning `x.ptr` would look a little nicer.
