Document C<local *STDOUT> as an alternative to C<select ... select>
If one needs to temporarily "capture" the output of C<print>, for example
as part of a unit test, the classic "obvious" approach has been to use
C<select> before and afterwards, to set a different default output handle
and the restore the previous handle.
If one is already in the mindset of C<select>, it might not be obvious
that C<local *STDOUT> is alternative way to achieve the underlying goal,
and might be clearer and more robust. Hence add it as a suggestion in the
C<select> documentation.
For: https://github.com/Perl/perl5/pull/19225; reconciling different
approaches developed by @nwc10 and @leonerd.
