OK, so please explain the big difference between appending to a string
and concatenation :-)

Most of the time spend in coping strings in memory as result of string
concatenation could be eliminated if you have to think before you do:

print $string1.$string2;

or

print "$string1.$string2";

As both of these are inefficient compared to:

print $string1, $string2;

or

printf "%s%s", $string1, $string2;

unless perl has very clever optimizations.  Thus I think that you does
not need string interpolation in BETA, as this tends to make programs
inefficient.  Think of strings as immutable objects, and you'll write
more efficient program.
