With my proposal, Derek's code would be faster when not debugging. It would
avoid all the "if vUnitTesting..." tests when debugging is turned off.

With my proposed solution:

-- math.e
constant vUnitTesting = find("-unittest", command_line())
include assert.e as assert

if vUnitTesting then
    debug 1 -- instead of a 'with debug' use 'debug X' where x is true or
            -- false (default setting)
end if

---------------------------------------------------------
global function abs(object pData)
---------------------------------------------------------
    object lTemp

    if atom(pData) then
        if pData >= 0 then
            return pData
        end if
        return -pData
    end if

    for i = 1 to length(pData) do
        lTemp = pData[i]
        if atom(lTemp) then
            if lTemp < 0 then
                pData[i] = -lTemp
            end if
        else
            pData[i] = abs(lTemp)
        end if
    end for

    return pData
end function

    .assert:assert(abs(0), 0, "abs0")
    .assert:assert(abs(3), 3, "abs1")
    .assert:assert(abs(-3),  3, "abs2")
    .assert:assert(abs(3.21),  3.21, "abs3")
    .assert:assert(abs(-3.21),  3.21, "abs4")
    .assert:assert(abs({1,-2,3,-4}),  {1,2,3,4}, "abs5")
.assert:assert(abs({1,-2,{3.1,-3.2,-3.3},-4}),  {1,2,{3.1,3.2,3.3},4},
    "abs6")

Those last lines are skipped over as comments without the need for an if
statement. Of course, the interpreter now has to check for {"--","."} if
debug is turned on instead of just "--".

Just a thought. Looks like it could work.
