No, you're right. I guess I was still carrying my memories from the
initial implementations, which did take a few seconds. The current
version takes ~0.3 sec on my machine if byte-compiled.

While that's far from pleasant (for a lot of people, +0.3 sec of startup
time would be noticeable), I guess it's reasonable enough. After all,
the user will be warned in the docstring about this caveat.

I agree.
