+#
+# Column 2 contains the string to be matched.

+# Column 3 contains the expected result:
+# y expect a match

+# B test exposes a known bug in Perl, should be skipped
+# b test exposes a known bug in Perl, should be skipped if noamp
+#
+# Columns 4 and 5 are used only if column 3 contains C<y> or C<c>.
+#
+# Column 4 contains a string, usually C<$&>.

+# Column 5 contains the expected result of double-quote

+# Column 6, if present, contains a reason why the test is skipped.
+# This is printed with "skipped", for harness to pick up.

+# Blanks lines are treated as PASSING tests to keep the line numbers

+# evalled; so something like a\"\x{100}$1 has length 3+length($1).
