[Pdx-pm] Not what I expected

[paull at peak.org]

Ok, the parser seeing it as "sort block list", explains the observed
behavior of not sorting and not uniquifying.  Now explain why it is allowed
to arrive at the "sort block list" conclusion.  The parenthesization of
uniq's arguments should preclude that interpretation.

My read of perlop says functions with parenthesized arguments are at the
top of the precedence table.  sort should not be able to take this

   sort uniq( @list )

and turn it into

   sort \&uniq @list
