Hi there,

I think this is a documentation bug.

Strictly, those words are true -- you *can* use the named or positional
captures in other directives. It does not say that you can use them in
this same directive. (Or at least, it is possible to read it that way,
if you really wanted to.)

But practically, it should state that the resulting value can be a string,
or can be a variable or a named capture, but cannot be a positional
capture. (Or whatever the actual restrictions are.)
