This is one way to simplify host function definitions, allowing to skip
host_context
parameter and using lambdas with captures.Another way could be having another host function pointer type like
HostFunctionWithoutContextPtr
suggested in #716 (review) (it would not allow lambdas with captures.)But I think leaving C++ API with none of these might be the least confusing, and most consistent with C API.
