Examples With Extraneous Context
array_var aMagicNumberToString
string_var slot
let aMagicNumberToString := Ar_Map 2::"Upper Body", 5::"Weapon"
if eval Ar_HasKey aMagicNumberToString, 2
; True, the array has the key: 2
let slot := aMagicNumberToString[2] ; I know this is safe
endif
if eval Ar_HasKey aMagicNumberToString, 5
; True, the array has the key: 5
endif
if eval Ar_HasKey aMagicNumberToString, 13
; False, the array has no key: 13 (or any except 2 and 5 in this case)

Exactly the same with a "stringmap"
array_var aStringToMagicNumber
int iMN
let aStringToMagicNumber := Ar_Map "Upper Body"::2, "Weapon"::5
if eval Ar_HasKey aStringToMagicNumber, "Upper Body"
; True, the array has the key: "Upper Body"
let iMN := aStringToMagicNumber["Upper Body"] ; I know this is safe
endif
if eval Ar_HasKey aStringToMagicNumber, "Weapon"
; True, the array has the key: "Weapon"
endif
if eval Ar_HasKey aStringToMagicNumber, "Another"
; False, the array has no key: "Another" (or any except previous two)
endif
