Yes, that's deliberate. If you use an ordinary `when` (with its statement(s) on the right) then P6 assumes it should succeed with the value of the last statement of the matched `when`. To succeed means to leave the block and return that last value if the block's value is being kept (eg via a `do`). If you wish instead to proceed to the next statement rather than succeed, you must write `proceed`. Conversely, if you use a modifier `when` (with its statement(s) on the left) then P6 assumes it should proceed as explained above after matching. If you wish instead to succeed as explained above you must write `succeed` (with a value unless you wish to succeed with a value of `Nil`). This is great bit of language design work. Thank you Larry.
