What is the proper way to do that? It seems like everything else just warns on wrong version?

warning = VyperException(
"tried to use block.blobbasefee in pre-cancun",
self.expr,
)
vyper_warn(str(warning))

elif key == "block.prevrandao":
if not version_check(begin="paris"):
warning = "tried to use block.prevrandao in pre-Paris "
