I agree, because a typed command in the standalone interpreter does
form a chunk, and yet:

stdin:1: unexpected symbol near '#'

Ah, so perhaps it should say it skips the first line of a _file_...
When I read Dirk's first message, the first thing I tried was:
local fn, err = loadstring([[#ignore
print("hello")
]])
if fn then
fn()
else
print(err) --> [string "#ignore..."]:1: unexpected symbol near '#'
end
but now I see that loadfile and loadstring behave differently in this regard.
