Sadly, no.

If _ENV is not a table, it is an error.

`load` is clean. Look at the nested brackets for its arguments.

ld [, source [, mode [, env]]]

That means one of:

ld
ld,source
ld,source,mode
ld,source,mode,env

Unlike debug.traceback:

[thread,] [message [, level]]

which means one of:

<nothing>
message
message,level
thread
thread,message
thread,message,level
