Subject: [PATCH] fix interoperability of `all` with hydra

Hydra add methods on Array.prototype which breaks the Array enumeration with for...in.
Use for...of instead
cf https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of#difference_between_for...of_and_for...in for details on the issue

without this fix, it is impossible to use both `await initHydra()` and `all` in the same strudel code. Strudel errors with "Error: got "undefined" instead of pattern."

example code: https://strudel.cc/#YXdhaXQgaW5pdEh5ZHJhKCkKCmFsbChwaWFub3JvbGwpCgokOiBzKCJiZCIp
