Even though I am a teetotaller, I do not want to stand between these two
folks and their Dom Perignon.  I do think, however, that what is crucial
is not what goes on inside the computer, but what goes on inside the mind
of the programmer.

Even if Ada 95 is "better" for some purposes, It is not better for all.

I used Ada for 6 years without ever using Tasking.  I had no need for
Tasking.  Last year a new project brought me to Ada specifically due
to a need for Tasking.  That is in a project situation where Ada
would otherwise be a total non-contender due to lack of a supported
compiler, particularly on the Macintosh.  (P.S., supported on the
Macintosh means the vendor stays up to date with each new toolbox
as Apple distributes it to thousands of developers six months in
advance of public release.)

Don't _ever_ turn up your nose at _any_ Ada user who lacks a need for
every bell and whistle ever invented.  Until you are able to point to
solid supported commercial compilers for every platform (in my environment)
and freeware compilers for every platform (for education environments),
every Ada convert should be received lovingly regardless of version
affiliation. (By the way, most of my latest project is in Pascal, due
to widespread availability.  There is a bit of VAX Scan, however, to
convert between Pascal dialects on various platforms.  That is why
I love Ada -- compilers at least attempt to comply with standards.)
