It's our classic idiom for loops: 

for($i=0;$i<10;$i++) {
  &do_something;
}

However, when we actually start to use the index, 

for($i=0;$i<10;$i++) {
  &do_something($i);
}

[download]
we frequently see various addenda to get it from "0 - 9" to "1 - 10". 
for($i=0;$i<10;$i++) {
  &do_something($i + 1);
}

Luckily, in perl, we have the flip-flop '..' to make things look like 

for $i (1..10) {
  &do_something($i);
}

which allows us to stop resorting to index manipulation.

If we do not need the zero, then why shouldn't we change the base? You know, $[, that fun yet spooky variable? Yes, making changes to it is not recommended. It might break a good number of things, and changing is now considered a compiler directive, so why make it available?
