It would be better, for compatibility purposes, to put it as:
A global variable (not a function) that holds a string containing the
current Lua version. The current value of this variable is "|Lua 5.3|".
That way a script can safely assume _VERSION contains the Lua version, or
tell if an implementation deviates from standard Lua. _VERSION == "Lua 5.3"
would be true in Lua 5.3, and any other Lua 5.3 implementation, but if a
fork of Lua 5.3 appeared, it would be encouraged to change _VERSION from
"Lua 5.3" to (e.g.) "LuaFork 1.0".
This would fix LuaJ being stubborn [1].
