Re: Elaboration order

[dewar@cs.nyu.edu (Robert Dewar)]

"   More important, it is possible to write a legal (Ada 83 and 95)
program which reads input from a file, command line, or even a
terminal, before the main program is called.  If you work at it
(exercise left to the reader) it is possible to write the program so
that there are two different interesting and legal elaboration orders,
and inputs that cause Program_Error with one elaboration order excute
successfully with the other.  Of course, for toy examples, there is
an equivalent program which doesn't raise Program_Error.  But for
embedded applications, it can be the case that various peripherals
have to be brought on line in sequence and with fairly tight timing
requirements."

This sounds VERY bogus, I would NEVER do this kind of initialization
at elaboration time -- this is NOT what elaboratoin is intended for,
but rather, in my book, a gross misuse of the concept!
