I'm invested in the amusement of the whole procession, but all the while
I'm thinking that command substitution inside a for loop is basic
shell syntax from POSIX:

   $ for x in $(echo a b c) ; do echo $x ; done
   a
   b
   c

so it's either a PEBKAC or some obscure version-specific Zsh problem 
nobody cares
about any more.
