Making escape (\) ordinary in double quotes

sg has asked for the wisdom of the Perl Monks concerning the following question:


Rather than writing:

{ my $foo = "Ignore the \\slash, expand $boo."; }

is it possible to do something like:

{ # do something to get perl # to treat '\' as an ordinary character # so that one may write: my $foo = "Ignore the \slash, expand $boo."; }

    sprintf does not alter the interpolation behavior of a double-quoted string, but it does provide all the interpolation capability of double-quoting – and more! See the many format specifiers in the docs.

    >perl -wMstrict -le "my $foo = 'Foo'; my $bar = 'Bar'; ;; my $x = sprintf 'ignore \slash, expand %s, %s.', $foo, $bar; print qq{'$x'}; " 'ignore \slash, expand Foo, Bar.'

    You can use q/STRING/

     my $foo  =  q{Ignore the \slash, expand} . $boo;

    You can check Quote-Like-Operators

    If you tell me, I'll forget.
    If you show me, I'll remember.
    if you involve me, I'll understand.

    You can concatenate the variable along with the string containing '\' in (') single quote. Ex

    my $foo  =  "Ignore the \slash, expand '.$boo;
