Lets say I have a struct or a handle object with many properties, so that calling a property with a dot is time consuming (it is done millions of times ever run)
is there a way to asign a handle to the property so that I can call it directly?

The only way I can think of is to make that property contain an object of a handle class. Other than that, no, because you can only directly refer to objects, not to their properties.
If the indexing is the problem, why not store the value in a variable? I can't imagine any user interaction generating changes millions of times.

Perhaps a persistent variable to create a makeshift dictionary would do the trick?
That way you can use ismember to look up the index in your cached data. You can even implement a counter that refreshes your data every X times.
Also, what do you think the chances are that I made a typo in my own name?

Thank you again for your answer Rik :)
Your answer looks like a good workaround, albeit a bit dirty. I will try it
