What could be better than an if/then statement? When using a "next repeat" command there's bound to be a conditional _expression_ somewhere.
I don't want to put an if/then block around a decent chunk of code when I can simply do this beforehand:
set myCondition to CheckResult() if not myCondition then next repeat.
This way, I don't my code that follows indented within an if/then tell block. It's the nesting that I want to avoid.
Here's another illustration of the repeat 1 trick.
The Next repeat command (if such an animal existed in appleScript) would look like this:
if foo < 0 then next repeat
And there wouldn't be a need for the inner repeat loop. But you would still need the if/then
repeat with x in {1, 2, 3, 5, 6, 7}
repeat 1 times
set foo to x - 5
if foo < 0 then exit repeat
display dialog x
end repeat
end repeat
