Yes that’s a very good idea and gives us more control (C++ and Swift allow explicit capture groups for example). In this example though would it even matter? The idea of capturing a loop iterator before the loops runs doesn't make sense to me. Maybe it should even be illegal or give a warning since it’s so error prone.

Speaking of that the Extended RTTI branch I did is over a year old I think now. Probably no chance of merging that without serious work. Michael got the RTL stuff done and tested everything but I’ve nearly forgotten about it since and I don’t know where it really stands. Hopefully that can be merged before it gets even more stale and decrepit. :)

Yeah I get this now. I was just being dumb with threads. The capturing isn’t even the most of my problems here.
