I will spend some time in the next couple of days to familiar 
myself a
bit more with he electric modes and can hopefully weigh in as 
well.

If we can patch electric.el and make this change simpler it is 
still
preferable imo.

Will try that, thanks.

(syntax-ppss) here is: (0 nil 1 nil nil nil 0 nil nil nil nil)

"""

"""

So does not see it as inside a string.

The triple quotes can either be a heredoc or a embedded template 
if
prefixed with ~H.

My current "working" version is here: 
https://git.sr.ht/~whk/emacs.
I rebase on there quite often though.
