Personally, if binary f-strings did struct packing by default, I'd want
to use them all the time.

That appeals to me, too. There are a number of practical problems that
would need to be worked out. We can argue those later :)

I think that's were I reach the limit of my "binary" experience in Python. But if people (here Steve) found it useful, why not? If there are problems that cannot be solved easily, we can do a V1 and later a V2 that includes the struct packing.

I guess it comes down to: what would the commonest use case for
fb-strings be?

To me, it's the same as for all f-strings: the bloody easy string concatenation of easily distinguishable parts.

I even have to admit I thought they were called format strings because they give format/structure to the resulting string. Well, now I know better (format refers to the formatting of the input expressions) but the analogy is still in my mind.

My other concern is non-ascii chars inside the braces in an fb-string.

What's wrong with them?

Best,
