Quite.  I think you missed the conditional mood of "I would ...".  I
would not store the slashes in the situation the OP described where,
apparently, it is worth breaking it down.  As you say, that vast
majority of the time there is no need.

But maybe it's worth asking "do you really need to do this?".

I'm not sure in this case, but James Harris usually posts after checking
documentation and so on, so it's likely he knows the standard path
functions.
