Hi,

I noticed in druntime this template is used often:

package template DECLARE_HANDLE(string name, base = HANDLE) {
     mixin ("alias " ~ base.stringof ~ " " ~ name ~ ";");

The disadvantage is, IDEs like IntelliJ are not able to find the symbols using this template e.g.

mixin DECLARE_HANDLE!("SC_HANDLE");

What is the benefit of this template?
Why can't we just use
alias HANDLE SC_HANDLE;

Most likely it's a direct translation from a C preprocessor macro.
