But -- while we're at it -- am I the only one who finds processing<br>
script files in general to be full of a lot of black magic? (Note that<br>
I'm referring to script files here, not proper algorithms). When<br>
refactoring processing to c++ I kept the script syntax unchanged from<br>
2.x as much as possible (with the exception of the sinks, which I<br>
cannot work out how to improve - save for re-creating a dummy<br>
VectorWriter object that wraps a bunch of stuff up). But to me it's<br>
*always* been rather un-python-like how parameters and outputs are<br>
defined in comments, how some variables are automatically created, how<br>
some output variables are expected, etc.</blockquote><div><br></div><div class="gmail_default" style="font-size:small;display:inline">Very good point!
