GeneralTemplate specializations are the new LISP Pin

If LISP stands for Lost In Silly Parentheses, then really, C++ should be renamed LISTS - lost in silly template specializations.

I've got a caps member of draw sources or targets which dictates the type of features it exposes. Then you implement methods which provide those features, so like, if you claim in your caps that your class supports "async" you are expected to provide XXXX_async() versions of your GFX draw source/destination methods.

GFX then chooses the most appropriate mechanism to complete the drawing operation you gave it based on the capabilities of the draw source and the draw target. So for example, if you have two in memory bitmaps of the same pixel format, you can basically memcpy one to the other, but if the destination is a display adapter, you may be able to transfer it via DMA, or failing that, you might be able to batch it if the destination supports it and if you can't do that you'll just have to do a standard pixel by pixel copy.

Well, this is all had through the magic of template specializations but in some cases its creating templates with more than half a dozen boolean arguments, wherein each **unique combination** of bools is a different specialization. All this because I need the compiler to prune out method calls that won't actually compile to anything and aren't valid on a target. - like XXXX_async() calls on a target that doesn't support it.

And now I'm lost, and it's time to see if I can refactor. I've got a towering combination of specializations that getting to the point where I can't follow which one is getting called, and now the results aren't what I expect (the one I want to be called isn't being called) and I can't trace why because the debuggers on these devices are crap.

This should be fun. Geez. Unsure | :~
