The documented ones I'm aware of are here:

https://dlang.org/spec/garbage.html#gc_config

https://dlang.org/spec/module.html#order_of_static_ctor

They definitely should be collected in a single location.

Look for the usage of the function `rt_configOption` in the D 
runtime.

Ex. for `trapExceptions` you can find it in dmain2.d used in the 
function `parseExceptionOptions`.

I don't think there are any official documentations of all the 
different runtime configurations, which I honestly believe there 
should be.

But by looking at usages of that function you'll be able to see 
somewhat what options are available.

I'm not sure if there are other functions related to it either, 
there probably are, so this probably doesn't cover it all.
