coroutine explanation

	//coroutine pseudo code explanation
	<hio> Okay I think I understand now why it's so hard for me to grok this, there is no regular programming API for this. Right? Who is supposed to offer an API for this, is this supposed to come from the compiler, like GCC?
	<hio> i think not, many people do create their own coroutine libraries so it's clearly not necessary to deal with the compiler
	<hio> but there is a lack of programming api surface, like.. C doesnt expose this stuff right?
	<hio> or is it the OS that doesnt expose it properly?
	<hio> I think it is probably the OS in combination with the system C library that should be offering an API to interact with the current stackframes etc. right?
	<hio> I feel like this isnt even a "low level" problem necessarily, you just need to get some reflection type access in your language and C/c++ dont have that so it's awkward and weirdly complex, like here c# actually allows access to stackframes: https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.stackframe?redire
