how do I do a literal string in the target of a regex?

[ToddAndMargo via perl6-users]

Hi All,

I am trying to change
     /

into

     \\\

This works:


$ echo "a/b/c/d" | raku -ne 'my $x=$_; $x~~s:g|$(Q[/])|\\\\\\|;print $x 
~ "\n"'
a\\\b\\\c\\\d


But this does not:

$ echo "a/b/c/d" | raku -ne 'my $x=$_; $x~~s:g|$(Q[/])|Q[\\\]|;print $x 
~ "\n"'
aQ[\]bQ[\]cQ[\]d


How do I put a literal string in the
target of a regex?

Many thanks,
-T
