Hello everybody.

I started to study the D programming language and i write same 
small library which use templates(generics) active. So i have one 
question, how can i get default value for template(generic)? May 
be something like this:

T someMethod(T)(bool someCondition){
     if (someCondition) {
         // ... do something and return result
     } else {
         return default(T);
     }
}

I solved this problem with help small hack:

T getDefaultValue(T)(){
     T default_value;
     return default_value;
}

But i don't like this solution and i don't sure that it is work 
in all cases. I want to use standard mechanism if it is exist.

With best regards.

PS: Sorry for my bad english. =)
