add an example of programatically creating a named tuple

[KristofferC]

This seems to be relatively unknown.

Version without comma works as well (;zip(keys, values)...)

Thanks for comments, updated accordingly.

I was just going to propose a patch for this. It's not on v1.2
But you've done it for v1.3 (or v1.4)
Thanks.

Forgetting this leads to loss of time every time you miss it. Quite often in fact!
It is not so easy to find in docs. An extraline in docstring could do the job.

And because NamedTuple{keys(itr)}(values(itr)) is not a good friend gift.

One could patches

!!! NamedTuple `nt` can be reconstruct from iterator `itr` yielded by `pairs(nt)`
with the syntax `(;itr...)`

...

julia> itr = pairs((a = 1, b = 2)); (;itr...)
(a = 1, b = 2)
