Well, it's quite complicated to do. I have to manually unwrap
each and all function template, then pray for the compile-time
optimization gods that they'll be inlined.
This is so annoying, that I might issue a DIP...

You can do that with either
- `static if` inside the body [1]
import std.traits;
void foo(T)(T t)
{
static if (isIntegral!T) {}
else static

There are different ways of doing that. I'd say this one is easy
to follow:
import std.stdio;
void print(T)(T entry) if(is(T==string) || is(T==int))
{
For example, I want my function template to only accept integer
or string;

What you are describing sounds like regular reference counting.
All resources (i.e. windows) are pinned somewhere in memory. Its just
that you have to use special API's to destroy them rather than free.

Is there any elegant/smart solution to reference counting
resources without ever freeing any objects?
When the ref hits 0 it should free some other resource that isn't
memory...
Resource[10] resources;
resources[3].inc; // 1 ref - 0->1 transition enable some feature
resources[3].dec; // 0
11 matches
