 Use existing variables whenever possible:

 Limit the scope of variables to `local` when within a function.
 
 When declaring a global variable, be explicit and do it using `typeset -g`. This avoids warnings when `WARN_CREATE_GLOBAL` is set:
 ```diff
-- : ${VAR=1}
-+ if (( ! ${+VAR} )) typeset -g VAR=1
+-: ${VAR=1}
++if (( ! ${+VAR} )) typeset -g VAR=1

 Use POSIX syntax:

 NOTE: There *is* a difference between this and ksh style, but unless you know what it is and you're **sure** you need it, use POSIX.
