No, I don't agree. The docs say very clearly

since "split" does change x (into an array, and to a different value), 
you're breaking the rule, and can't expect this to work.

Passing x as a parameter to the function passes a *copy* of the data, 
and hence avoids breaking the rule.

I'm not sure what Rev intended by the phrase "cause a script error" - it 
certainly doesn't cause the script to stop with the error box, in any 
example I could think of - but it does produce "unexpected" results in 
some cases.
