I'm not sure of a good solution for this.  The problem is that
the {$var} markup rule replaces {$:test} with the value of
the $:test ptv from the current page.  In this case, that value is
"{$:test}"... so, we replace {$:test} with itself and then
do the markup rule all over again.

The only "solution" I have so far involves hard-coding checks
for specific PTV patterns as part of returning PTV values...
and I'm not sure that's a good robust answer.

Note that there are other cases that can cause a problem:

    alice: {$:bob}
    bob: {$:alice}
