Drawback of calling a form method from another form?

[Kaptan]

I was wondering if there is any performance difference in the following 2 scenarios:

1. calling a form method from a method on another form
2. calling a global method

I have a couple of methods on forms that call a method on another form. Some methods are logically grouped under a specific form. But in all of the methods I always avoid using form.x.controller stuff because of the UI updating that isn't needed.
It keeps bugging me that I still have 'forms.x.method()' stuff in my methods, it doesn't feel right because whenever I start lines with 'forms.' I always assume that this has a UI consequence. But is that the case when calling methods? Should I put those methods in globals? (and accept the memory usage in globals, and loose the logical grouping) Am I overseeing something obvious or is this already the best practise?

I'd say that calling forms. has the overhead of the form being loaded. So yes, that should be (slightly) slower the first time you call a method on form.x. I can't imagine you will notice any difference though.

Ah yes of course
That being the case, then it's a pity that you can't call a form method without loading that form. Would love to have something like 'script.' next to 'form.'.

Thanks for the reply!
