# There are five columns, separated by tabs.
#
# Column 1 contains the pattern, optionally enclosed in C<''>.
# Modifiers can be put after the closing C<'>.
#
# Column 2 contains the string to be matched.
#
# Column 3 contains the expected result:
# y expect a match
# n expect no match
# c expect an error
#
# 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
# interpolating that string after the match, or start of error message.
#
# \n in the tests are interpolated, as are variables of the form ${\w+}.
#
# If you want to add a regular expression test that can't be expressed
# in this format, don't add it here: put it in op/pat.t instead.
