Re: Interpolating backreferences in an eval

[gone2015]

Try:

     print eval qq{"$to"}, "\n";

...eval comes in two flavours: (a) eval BLOCK -- in which the BLOCK is compiled in the usual way, and the eval is a way of trapping die; (b) eval EXPR in which the result of the EXPR is parsed and executed at run time. See expr.

Of course, you could also:

     my $q = $1 ;
     $to =~ s/\$1/$q/g ;

Thanks you! It works.

I've tried eval "$to" but got a syntax error that I couldn't understand. Seeing that eval qq{"$to"} is the same as eval "\"$to\"" I can understand now what I've done wrong.
