This is for C++, but the logic is language agnostic, with some 
work, you could make it work for D, (strip the C++ compile part, 
and reuse the parsing and process patching patch). I've seen 
people make it work for Zig, this is much better than shared 
library reload, since the user has no build script to duplicate 
or code to separate.

It's ARM in that example, but they plan to make it available for 
all the supported targets, built right in the compiler.

The day they land that feature will be the day I switch.
