Reading that again, I'm thinking that f never gets turned
into a function. Anyway, Matt wrote:

But that prints "foo", rather than printing the return value
of the function returned by f (namely nil).
I only came up with that example, because I didn't
understand how the
foo = -L "line 1" "line 2" "line 3"
code worked. I think I've got it now, though. The
preceding line of code had a certain behaviour that I
couldn't duplicate, but now I've duplicated it with:
function f(x)
if x then
print(x)
return f
end -- if
end -- f
foo = f "bar" "baz" "qux"
which prints "bar", "baz", and "qux" (and assigns f to foo).
