Firstly there was a typo in the example - but it also seems I was wrong. Its
an old habit that perhaps was justified a long time ago?

function countLines someLines
    repeat for each line someLine in someLines
      add 1 to lineCount
    end repeat
    return lineCount
end countLines

I do remember having errors in handlers where an a variable that was first declared/initiated inside a repeat loop (in this case "lineCount") would return the literal text "lineCount' and not empty if the repeat loop was never entered into (ie someLines) was empty - maybe it was just in a version
of the debugger - no idea.

Well one bad old habit fixed :)

Maybe you are thinking of a problem I have had which
was dealt with by declaring the variable just before I
do the repeat line.  When I am going to add to a variable
I always make sure it has something to add to first.

put 0 into lineCount

function countLines someLines
    repeat for each line someLine in someLines
      add 1 to lineCount
    end repeat
    return lineCount
end countLines
