[fpc-pascal] with statement using mulltiple objects

on compiler implementation: 

I read in this list that the group
lost months due a "with" problem. 

People use "with", and I guess lot
of people use it! 

I checked the reference
and there is not any warning ... just: 

The statement 
With A,B,C,D do

is equivalent to 
With A do 
 With B do 
 With C do 
D do Statement; 

without any warning ... 

(and there is noting about
the syntax with xxx[ nn]^ = A do ... describe by someone earlier) 

I am
not telling that an implementation in the compiler should be of higher
priority!!! I appreciate a lot the great job that has been done, and is
still going on! I know I won't be able to do it!!! I'ld really like to
contribute ... but ... my age and qualification ... won't help very

But I am pretty sure that this implementation could have saved
many time to many people (as one of the developper wrote) ... and still
may save. 

But as it has been written ... we may be out of subject!

error when may be confused. (but let configure it!)
