Just as a matter of personal preference, I -hate- C++ code that has
variables shuffled in with code this way!  I find it extremely
difficult to read.  While I agree that forcing all variables to be
declared in one place is unnecessarily limiting, I personally find it
much more clear to declare -groups- of variables near where they will
be used (by corresponding -groups- of program statements), rather than
dropping them in one-by-one just before they are needed.  I think the
Ada way gives exactly the right fineness of conceptual granularity.
