I also find it useful to combine the global macros before the loop (esp. if there's repetition in the elements), e.g.

**************!
global cash "pocket asdf bank"
global check "bank"
**
global all: list global(cash) | global(check)
di `"${all}"'
**
foreach y of global all {
display "`y'"
}
**************!
