This solution uses a loop too. If possible I would like to avoid looing through
the objects.
I had something like using indices in mind. With this I would have something
like this:
myobjects: make hash! [] ; using index,object pairs
= [1 obj1 2 obj2]
myobjects_names: make hash! [] ; using data-field, index pairs
= ["robert" 1 "carl" 2 "joachim" 3]
Searching the object with a name joachim would result in object ID 3, than
makeing a lookup in the objects and get the object with ID 3. I hope you know
what I mean.
With this you will have an index for each data-field you want to search for.
Remembers me on the good old databases ;-)) Robert
