In plain unmodified hzoli10.3 the unadorned backslash does exactly that.

$ ./zsh -fc 'echo $ZSH_VERSION
             array=(a b c d e)
             echo $array:s/\/\&-\&/
            '
2.6-beta10-hzoli10.3
a-a b-b c-c d-d e-e
$

Is this just another undocumented feature? Since there's no real need
to escape the delimiter--just choose a different one--the backslash 
seems one of the best choices to denote "substitute whole string/ele-
ments of array" to me. 


Sincere apologies for my GNUisms breaking hzoli10.2.
Please forgive me.

BTW it is "substitution", isn't it?
