It depends. With Lua 5.3, I tried to set `string.gsub` to a value `x` and
test some things with it. Invalid argument and other errors gave an
error with the function `x`, but the traceback showed it was an error
with the function `string.gsub`. So, the function does have a name
associated with it, but it does also include the name used when
referencing that function. The traceback - at least with Lua 5.3.1 -
will show that the error happens when the value with the associated
name is called, but it shows that the error is in the function with the
original name.
I've attached an example script if you want more of a reference.

Tracebacks (and the debug API) show the name of the variable that
referenced the function.
