cating that "\p" maps to "\c\l" on Windows, equivalent to "\r\n". Currently, Nim allows the use of cap­ ital letters in place of the lowercase ones for these control characters, namely '\L', '\C', '\N' e. $c for an arbitrary character or $s for optional white space. The optional white space is not cap­ tured, just ignored. With the use of $s, our program already allows a more flexible input string: function uses as a third argument a string, which is used for replacements and in which we can refer to cap­ tured groups with the symbols $N, where N is the index of the captured group starting at one.
