I am currently learning Perl by trial/try/error, and I have a Python background. The purpose of the program of the subject of the question, however, is to find out what is idiomatic Perl and what is not. I don't want to end up writing Python in Perl. This is my program: 
use strict;
use warnings;

print "RegEx Engine 1.0\n________________\n";
print "Gimme a string: ";
my $str = <STDIN>;
print "Gimme a RegEx: ";
my $pattern = <STDIN>;
my $answer = eval("\"$str\" =~ $pattern");
if ($answer) {
    print "Yes!";
} else {
    print "No.";
}
print "\nkthxbye\n";

Is this good/idiomatic/bad/ugly/encouraged/discouraged/ Perl? (Note: I am using Perl 5)
