I was probably a bit too critical in my last e-mail.  I'm sure it's 
possible given SetLength is an intrinsic rather than a real subroutine.  
Is it possible to add an extra parameter and have the compiler detect 
whether it is for setting a length or specifying "no initialisation"?  
I'm just a tad concerned about avoiding additional overhead should the 
parameter be omitted and the effect of explicitly specifying False 
(since the actual parameter could be a Boolean variable and the internal 
"set_length_no_init" routine will then require an extra check to see if 
this parameter actually is set to True in order to ensure correct 
behaviour).
