It would be nice to get some feedback or at least any reaction to this.

So, I'm not as confident here because I don't use fibers but I think it is a good idea too.

One potential issue I see here is that Fiber.call actually documents how unhandled exceptions are treated (calling context resumes), and it even has a switch to set that behaviour. Is rt_trapExceptions actually documented anywhere?

[mathias-baumann-sociomantic]

Only documentation I know of for this is

druntime/src/rt/dmain2.d

Lines 142 to 144 in 15a2274

	// This variable is only ever set by a debugger on initialization so it should
	// be fine to leave it as __gshared.
	extern (C) __gshared bool rt_trapExceptions = true;

I can change the docu for Fiber.call to mention the behavior when rt_trapExceptions is set
