Hi all,
I'm trying to render a diet template out to a WebSocket as a
string to be inserted into a specific portion of the currently

Please consider the following
struct arc(T,U)
{
T some_var;
U someother_var;
}
/* things */
class myclass
{
this(){}
~this(){}
void MYfunction()
{
arc!(string, string[]) * a;
a.some_var = hello;
}
}
void main()
{
c = new myclass();
c.MYfunction();
}
This leads to a
Also, (*c).MYfunction() is leading to segmentation fault
sorry, I meant (*a).some_var
not (*c).MYfunction()

I don't know what are you trying to achieve, but if that's what
you want, you can do:

No. The uninitialized ones get their .init values.

That already works with structs. You don't

You can initialize in constructor this(), but you can't
initialize partial

Actually, that works too but members must be initialized from the
beginning. The trailing ones are left with .init values:

I got to typing one day and came up with this. What it does is
search an aggregate for a member named match. If it's a direct
member, it evaluates to that. If it's not, then it searches any
aggregate type sub-members (deep members) for match. If there's
only one deep member tree with match, it
One way I've used it in code
struct MapBy(T,string key) if (hasDeepMember!(T,key)) {
alias key_t = DeepMemberType!(T,key);
private const(T)[key_t] _map;
bool has(key_t id) const nothrow {
if ((id in _map) != null) return true;
else return

Not that with int choice, you'll get a compiler error because
it isn't a compile constant. I'm not really sure about

Philippe Sigaud:
alias for templates gives you a 'symbol' parameter: you can

Not built-in types (int,...) which are keywords and *not* valid
identifiers.
I remember some persons have asked for built-in types too to

There are a few problems with my implementation so far...
