Subject: priority problem of ":|" and ":*"
Date: Mon, 24 Dec 2012 18:52:41 +0800	[thread overview]
Message-ID: <20121224105241.GA24051@localhost.localdomain> (raw)

hi,

I believe the new ":|" and ":*" should be in Rule 7 Modifiers of
paramter expansion, so this looks like a problem in priority:

    % a1=(a b c);a2=('a b c');print "${a1:|a2}"
    
    % a1=(a b c);a2=('a b c');print "${#a1:|a2}"
    3

in this, the priority should be "5 Double-quoted joining" first, then "7
modifiers", then "9 length". So 'print "${#a1:|a2}"' should output 0 I
think. And the ":*" has the same problem.
