Re: [suggestion] assert: accept functions as "message"-argument

[GrayFace <sergroj@...>]

I'm clueless why you would need it.
Compare:

assert(<condition>, function()
  return "hell".."o"
end)

to:

if <condition> then
  error "hell".."o"
end

Second is better in every possible way.

In your example of an externally declared function you can as easily 
make a function
my_check(something, errorcode)

Again it appears to be much nicer.
