Why would you fire someone for writing idiomatic D?

It was kind of a bad example given, but there are legitimate 
reasons to generate functions like that.

Ex.

mixin template Property(T, string name)
{
     mixin("private T _" ~ name ~ ";");

     @property
     {
         mixin("T " ~ name ~ "() { return _" ~ name ~ "; }");

         mixin("void " ~ name ~ "(T newValue) { _" ~ name ~ " = 
newValue; }");
     }
}

mixin template ReadProperty(T, string name)
{
     mixin("private T _" ~ name ~ ";");

     @property
     {
         mixin("T " ~ name ~ "() { return _" ~ name ~ "; }");
     }
}

mixin template WriteProperty(T, string name)
{
     mixin("private T _" ~ name ~ ";");

     @property
     {
         mixin("void " ~ name ~ "(T newValue) { _" ~ name ~ " = 
newValue; }");
     }
}
