python folding for classes fails on linebreaks in base list

[RonnyPfannschmidt]

when a python class is written like

class Demo(
        Base Fun):
    pass

then folding ignores it

What folding specifically? If you mean the fold arrows, those are only displayed if you have 2 or more lines with the same indentation or higher than the following line. In your case this is reversed (meaning the following line has an indent of 2 and the line after that has 1).

i see, then i missunderstood how folding is supposed to work with python.
a bit more syntax awareness would be nice (classes/function definitions)

[FichteFoll]

Well, that's how folding works everywhere in Sublime Text.

For syntax-based folding there is #101. Since I assume this is what you wanted to express, I'm closing this as a duplicate.
