ok, then that should be spelled out in the paragraph.  can you please add that,
something like, "all of these languages listed below have the exact same
conversion behaviour"

then it is clear.

otherwise it looks like rust is *implemented* in or by llvm, java, and SPIRV.

see how things have to be absolutely spelled out? no possibility for
english language ambiguity.
