This is really a good idea and the suggestion is helpful. However is not the first statement a little bit strong? I mean, i thought template haskell was working at least for some cases. The warning could be surprising for those who th works.

For me Haskell should never segfault, it's a horrible user experience. Therefore, TH in MacOs with a statically linked binary doesn't work.

Secondly, the statement is strictly true: we don't support TH in Mac OS with a statically linked binary: no one is working on fixing the problems, which involve bugs in the Mach linker in GHC.

Do you have any concrete suggestions?

I just saw it is exclusive for macos and it is not emitted for Linux. I would add a weak version for Linux as th cause problems in that os but we can wait to see what is the effect of alpine binaries

It seems hie-bios should be updated to 0.8.0 in stack.yaml's to get hostIsDynamic
