I don't think that argument holds water. Concatenation of dynamic structures
is a slow function in the first place. I am not a core developer, but I
consider that regardless how you do it, it will require a call to setlength,
which in turn will call the operating system to allocate memory for the now
larger structure. That takes much more time than a few assembly instructions
for a normal pascal procedure call.
