Is it wrong to use "out" for the sole purpose of informing the compiler 
that a function will set the initial value of a variable passed as the 
parameter? Or is it just a side effect? I use it all over the place in 
my programs. Is it safe to use with interfaces, ansistrings, dynamic 
arrays? Should I stop using it this way?
