perlre(1) seems to be missing information about substitution evaluations
with the /e option. The functionality is present in perl:
perl -e '$_=2; s/2/1+3/e; print'
But it is not listed in the base documentation. The modifier /e is
described in "Programming Perl", 4th ed, pp 186, 254-255. Could something
like the following be added?
