Until now I always used \invokepgfplotsforeach{1,...5} successfully. Since I have some nested dynamic code all using #1, #2, #3, etc., I wanted to name the foreach's variable #1 by using \foreach.

        \foreach \variable \in {1,3,5} {
            \addplot {\variable*x};

Unfortunately, even this MWE leads to the following error message:

! Paragraph ended before \pgffor@@vars was complete.

The same when I am using \pgfplotsforeachungrouped instead of \foreach. What is it missing?

    It's just in, not \in. – campa Aug 16 '17 at 14:42

As campa said in his comment:

It's just in, not \in.
