Single quotes don't interpolate. Double quotes do. For example, my $not_interpolated = '$this'; won't interpolate, but my $interpolated = "$this"; will.

But you may find it helpful to use qr// (as discussed in perlop). ...used as follows:

my %config = (
    URI => {
        regex => qr/^$method\ssip:/,
        sub   => \&request_line,
    },
);
