How about using an object? Like:
>> Person: make object! [
[ Name: "Rod"
[ Age: 37
[ Profession: "Developer"
[ ]
>>
>> person/name
== "Rod"
>> person/age
== 37
The words in a object is:
>> first person
== [self Name Age Profession]
and the values in a object is:
>> second person
== [
make object! [
Name: "Rod"
Age: 37
Profession: "Developer"
] "Rod" 37 "Developer"]
Where the first value is 'self, and the next three are name, age and
profession.
I hope that helps!
