"And for the viewers at home, the answers are...
@a =^+ 1; # evaluate each element of the list (1) in a numeric
# context and assign the resulting list to @a
# i.e. @a = $_ foreach +1;
@a ^=+ 1; # evaluate 1 in a numeric context and assign it to
# each existing element of @a
# i.e. $_ = +1 foreach @a;
@a ^+= 1; # add-assign 1 to each element of @a
# i.e. $_ += 1 foreach @a;
