while()

[MauriceMeilleur]

@frederik @justvanrossum Am I crazy, or did one of the recent updates of DB introduce a while() function that can replace save() and restore()? Perhaps I'm misremembering the name; in any case I can't find it here on the forum. Any help?

This is savedState() http://www.drawbot.com/content/canvas/state.html#drawBot.savedState

with savedState():
    # do something

This is more readable and clearer then wrapping code inside a save / restore statement.

@frederik Ah! Thanks, I had totally misremembered that.
