electric-pair-syntax-info calls (syntax-table) which is unaware of the
syntax-table text property.

electric-pair-syntax-info looks inconsistent. Part of it is based on
point (e.g. syntax-ppss) and part of it not.

(This bug report unfortunately got no response at the time.)

Do you have a recipe to reproduce whatever bug you're seeing?

I can't remember what I had in mind at that time.

But I imagine if ` and ' have word syntax but `` and '' are
syntax-propertized to behave like matching parentheses, then function
syntax-table is not the correct way to access syntax info.

The issue is not specific to elec-pair. Any program that needs to get
the syntax of the char at point needs to check the syntax-table property
first and then check (syntax-table).

Thanks for picking up this bug.
Leo

It's a bit abstract -- unless we have a concrete case to look at, it's
unlikely that there'll be any progress on this issue.

So I'm closing this bug report.  If further progress can be made, please
respond to the debbugs address and we'll reopen.
