# This pattern uses a lot of named subpatterns in order to match email
# addresses in various formats. It's a heavy test for named subpatterns. In the
# <atext> group, slash is coded as \x{2f} so that this pattern can also be
# processed by perltest.sh, which does not cater for an escaped delimiter
# within the pattern. All $ and @ characters in subject strings are escaped so
# that Perl doesn't interpret them as variable insertions and " characters must
# also be escaped for Perl.
# This set of subpatterns is more or less a direct transliteration of the BNF
# definitions in RFC2822, without any of the obsolete features. The addition of
# a possessive + to the definition of <phrase> reduced the match limit in PCRE2
# from over 5 million to just under 400, and eliminated a very noticeable delay
# when this file was passed to perltest.sh.
