So I guess we should ban 'C' as a variable name too. Who cares what
looks like C? Does that somehow bring along with it the problems in C?
How?
We already have A := "This" & " That", Why not also B := &"The other",
that makes it perfectly analogous with D := 1 + 2 and E := +3. (Yes, I
skipped C :-) Function "&" already has an established meaning in Ada,
why not use it for a (somewhat) similar purpose?
If that looks like C, you could always use
B := Ada.Strings.Unbounded_String."&"("The Other"); or B := "&"(A);
That doesn't look anything like C.
It sounded from Randy's message, that (some of) the problems were based
on defining a new operator ("#") and unrelated reuse of an existing
operator ("+"). This proposal fits in with existing Ada usage.
(Funny, today I was going thru Sun's (Oracle's) Java tutorial, and
several places they had something like "+ is used for addition, and oh
by the way, also for string concatenation".)
