In the light of this...
Building lang/llvm on macOS 10.13 ("High Sierra", the latest that will
install on this hardware) fails with an error described in
<https://github.com/llvm/llvm-project/issues/64472>. Upstream nominally
supports clang 10, but Apple's clang 10 objects to the
"std::optional(_expression_)" structure, as opposed to
"std::optional<T>(_expression_)".
Do you have any ideas on this?
Looking at the Makefile, we set USE_CXX_FEATURES=c++14 when
std::optional>T> appears to be a c++17 feature.
Cheerio,

(Please excuse my rusty c++ fu, the last time I wrote c++ code in anger
was half a life ago.)
