Wondering whether gobject may make python-vim API look like rather regular
python module and not like something ctypes-based with many implementation
details leaking.

It is locale and not unicode support, though they intersect. I understand
that locale support will break plugins, thus I asked only about unicode.
This is not about ranges, but about character properties.

I do not remember clearly, but was not it suggested to take PCRE syntax? I
do not remember any discussions suggesting taking PCRE and replacing parser
code, but I may have missed something.

All unicode properties. I guess you may use icu to fetch characters with a
given property into a collection. Maybe existing API allows faster variants.
It is useful for things like stripping diacritics or finding variable
names. There are more uses I cannot imagine thus there is no need for
restricting support to just some unicode properties unless there is some
technical reason for it.

It is not this. Problems solved include:
- Possible deletion of function that is referenced somewhere.
- Weird anonymous function names.
- Restriction for deleting functions being profiled.
- Using python callables as vim functions.
This list does *not* include partial application, not without lambda
subbranch.

I know it. It is not close, not a tiny bit. Main problem is not escaping,
it is shell itself. There is no way you can use system()/:! and not use
shell.

It is too smart about line endings.
