Ok. So in the following examples, would the 1st form; ${(s: :)EXEC}; be
preferred, since the documentation says using the 2nd form; ${=EXEC};
forces SH_WORD_SPLIT on; potentially leading to unexpected behavior later?

#! /bin/zsh
EXEC='/sbin/ifconfig eth0'
EXEC=(${(s: :)EXEC})
exec $EXEC

#! /bin/zsh
EXEC='/sbin/ifconfig eth0'
EXEC=(${=EXEC})
exec $EXEC
