Since we can't put a link statement and program on a single line, we implement a simplified inline sprintf so we don't have to deal with all the double quotes or substrings and offsets. If we'd needed to write multiple procedures on a line it can be done [[Icon%2BUnicon/Intro#Semi-colons| Semi-colons in the language intro]]

For the narcissist to work you must be very careful with whitespace. The following version works if it is given to standard input as exactly one line terminated by a newline character.
Note how the code takes advantage of Raku's ability to nest quoting delimiters.
