1)  I frequently use for loops in an interactive shell to act on arrays.
   Arrays are the easiest way to not have spaces breaking args
i.e.:
2)  I almost always start my scripts with a templated prologue:
----
>  cat ~/bash/template
#!/bin/bash -u
# vim=:SetNumberAndWidth
export PS4='>${BASH_SOURCE:+${BASH_SOURCE/$HOME/\~}}#\
${LINENO}${FUNCNAME:+(${FUNCNAME})}> '
shopt -s expand_aliases
alias my='declare ' int='my -i ' array='my -a ' map='my -A '
setx() { trap unsetx EXIT; set -x; } ; unsetx() { set +x;}
