This is AI 147, Conditional Expressions (as primaries).
http://www.ada-auth.org/cgi-bin/cvsweb.cgi/ai05s/ai05-0147-1.txt?rev=1.2

Yet another thing that makes Ada more attractive
for programmers who would not waste valuable time
for finding names, say write a small named function
that conditionally returs this or that.
Obviously, local functions are overly verbose
and explicative, they must be avoided at all cost.

Ada finally gets C's  ?:  conditionals!
Have you ever seen anyone using ?: in C or Perl in
a way that is obfuscating? Really?

Nah, it's nice!  We can even leave out the bulky
comb structure.  Just pairs of parentheses!
the Lisp fans will rejoyce, C programmers will
feel at home, done with a single stroke!

loop
   exit if (if N > 0 then M/N > 0 else M > 1);
   N := F(M, N);
end loop;

Not even Lisp or ML style let bindings are necessary!
Ah, fancy that! We've got more and more anonymous pointers,
free and easy,  why not free floating control structure
then?  I forget, it's a nice opportunity for tool vendors
to sell more style enforcment programs and language restriction
options.  They are learning ... :-)
