Value:

  VISKORES_STATIC_ASSERT_MSG(                                                \
    ::viskores::exec::arg::internal::ExecutionSignatureTagCheck<tag>::Valid, \
    "Provided a type that is not a valid ExecutionSignature tag.")

Checks that the argument is a proper tag for an ExecutionSignature.

This is a handy concept check when modifying tags or dispatching to make sure that a template argument is actually an ExecutionSignature tag. (You can get weird errors elsewhere in the code when a mistake is made.)
