How to translate idioms

Philipp Lenssen at Google Blogoscoped has posted a list of idioms written in code.

If you have a quibble with the format of these remember to
take(salt * .01); (That's one of his coded idioms.)

For the full list go to his page -- and for answers read his readers' comments where issues of syntax and well formedness (appropriately) come up a few times.
