All types in Lua, being first class values, are purely values - the name
only comes from the variable(s) the value is stored in.  As such, functions
(being values) do not have a name.  They may be stored in one or more
variables, each with a name, but still the function itself has no inherent

If you know that it is a global function, or know what table / namespace it
is in, you can iteratively search for a table entry with the same function
value, then print the name of this key.  Of course there may be more than
one, so you could print them all, or the first one or whatever
