How can I create a GUID in Vim?

Vim does not have a built-in GUID generator.

For the project I'm working on, I can rely on Powershell availability, so the following gives me a GUID string:

[guid]::NewGuid().ToString()

I call this in the substitution as follows:

%s/foo/\=system('[guid]::NewGuid().ToString()')[:2]/

While this works, it blinks a window for each lookup, and it is pretty slow.

I really want to create a GUID in Vim, portable and fast.

If you can rely on Vim Python scripting support available

:py import uuid
:%s/foo/\=pyeval('str(uuid.uuid4())')/
