I mean if in theory you were to inline that function variables code into the
function it would need to generate a new function (I guess the name also, so
the entire thing) because the function being passed in could change on per-call
basis (like a normal generic function)
quot;trunk" location so that it doesn't overwrite existing stable compiler releases.

I understand simple constant propagation cases but how does this apply to
inlining entire functions? I think C++ can do this with closures so it's
something worth looking in to for the future.

I just realized too late that the way I implemented this may be not the best
idea. If the class type had an ordinal representation then you could use a
no
he class if it didn't exist in the list. It's an
incomplete code snippet but if the class was another type it would be captured
there of course.

I may have spoken too soon and without thinking the through clearly (it's
getting late here!). For this to work we would need a unique ID in the
us what this type actually is also, maybe a dispatch table which wraps
the existing types or is it something totally new?

If anyone understands SDL I figured out how to get around this missing main
linker error and
look kind of like this:
for case monster as TZenChan in monsters do
TZenChan(monster).Dothis;
That syntax is not so nice but I like they're trying to help us manage class
