I dislike this usage, in commercial programming situations, usually. The
reason is well known: that it can often be confusing (or, at least, less
obvious) for programmers new to the library environment or project. I think
it's fair to say, also, that this sort of notation can be so 'quiet' as to
be overlooked, and thus a source of mistakes (which would have been avoided
with a 'louder' notation).
Given that the only reason (tell me if I'm wrong) is to abbreviate an
identifier, essentially, I feel it is rarely justifiable. If the programmer
feels that an identifier is too long ("Ada_To_Java_String" perhaps), it can
always be renamed (or subtyped or whatever) to a shorter, but still
meaningful, identifier ("A2Jstr" possibly).
One of the real practical strengths of Ada is its lack of obscure notation.
I'm a real fan (as you can tell :-) of this clarity.
