Writing your own assert function is quite easy:

function assert(cond, ...)
    if cond then
        return cond, ...
        local err = select("#", ...) == 0 and "assertion failed!" or ...
        error(err, 2)

The second parameter to 'error' tells it to ignore the 'assert'
function when generating a stack trace.
