Elaboration Question

[Hubert <herrdoktor@fumanchu.com>]

For a newcomer to Ada, elaboration is one of the toughest things to 
understand. My understanding is so, that if you have for instance a 
variable in the package body, say :

A : Integer := 0;

then this variable must be initialized at some point and that's what 
elaboration does.
The problem then occurs with the order in which elaboration occurs in 
different package that depend on each other etc.
There are pragmas for the programmer to take control of the elaboration 
sequence but I have the feeling that may complicate things. especially 
when you want to make a library that should be independent and that's 
supposed to be be released to others at some point.

So may question is, is it better to just leave those variables 
unitialized and then initialize them later for instance:

A : Integer;

PROCEDURE Initialize IS
BEGIN
    A:= 0;
END Initialize;

Would that be generally better?


Thanks
