Hello, what is the syntax for having constant in regular expression ? Such as

use constant (NL => '\n');
#check if there is newline in the text
my $txt = "foo \n bar";

if($txt =~ m/ # ???

/x)
{

}

Constants cannot be interpolated into strings like variables.
This applies to interpolation in regular expressions.  It's ugly,
but this works,

/@{[NL]}/
