You couldn't put `next`/`last`/`redo` in bare blocks either, at least not without adding labels. Bare blocks are loops that execute once. However, that's not a big issue because those commands are practically always used conditionally. Unlike bare blocks, `if` blocks aren't loops, so you can use `if ($cond) { next }` (but not `{ next if $cond }`). If you do have an unconditional loop control command (e.g. `{ ...; redo }`), label the loop (`LOOP: { { ... } redo LOOP }`) or use a unconditional `if` (`{ { ... } if (1) { redo } }`).

Notice that he didn't use any `my` variables?	[reply] [d/l]

Wait a couple seconds! What about `use vars()`? (ikegami's reply to a reply below made me think of it (because he had used it himself).) And you didn't even know bears could type.	[reply] [d/l]

Hmmm, you should probably all have a look at `Acme::Pythonic` [download] from Xavier Noria. There you only have to use one ';', namely in `use Acme::Pythonic;` [download] :) Of course, there still would be semicolons in strings and regexes or other non-statement places...
