Solution: Split a filename

Here is a possible solution to the task.

Code

if 'report.txt' ~~ / (\w+) '.' (\w+) / {
    say ~$0;
    say ~$1;
}

Output

report
txt

Comments

The first pair of brackets captures the base name into $0, the second captures the extension into $1. The dot between them is quoted so it matches a literal . rather than any character.
The ~ in front of each capture puts it into string context, so it prints as plain text. Plain say $0 would instead show the match object with its corner brackets, ｢report｣. Writing say $0.Str does the same as say ~$0.
