in a way, it's silly to compare speed at this level. Lingo is an
interpreted language, and as such is inherently slower than other,
system-level languages. If speed is a priority, Director and Lingo might
not be the best choice.
Of course one should optimize code as much as possible, but my point is
that the advantages one gets from using dot syntax outweigh the speed
disadvantages, especially when you compare both to other languages.
