If you remove the space between "<+" and "..." your example works just

Thanks for your hint.
Are there any chances to make the presented error message "minus: parse
error" easier to understand?
No, I think it would be difficult. Yacc-like parsers are not always so
helpful in this respect.
Would you like to support additional whitespace characters between the
brackets (<+, +>) and the ellipsis?
No, I don't think so. It's one concept, not < followed by dots.
By the way: Is the character U+2026 also accepted as a horizontal ellipsis
(instead of three dots) by the grammar of the semantic patch language?
No.
Anyway, you may also want to consider cases where the result of the
function is assigned to a variable that is unused.
Yes. - I'm also interested in further adjustments of the SmPL approach in
this direction.
How can variable assignments chains be properly handled?
You can specify whatever pattern you want. On the other hand, nothing is
done behind the scenes to help you.
