You might also want to give Nice::Try a try. It is quite unique and provides all the features of a trycatch block like in other programming languages.

It supports exception variable assignment, exception class, clean-up with finally block, embedded try-catch blocks.

Full disclosure: I have developed Nice::Try when TryCatch got broken.

You probably wanted one of the CPAN modules such as Try::Tiny:

use Try::Tiny;

try {
  # statement 1
  # statement 2
}
catch {
  print "Error\n";
};

Perl does not provide try or catch keywords. To trap "exceptions" thrown by die, you can set a $SIG{__DIE__} handler or use eval. Block form is preferred over string form, as parsing happens once at compile time.

eval {
    // statement 1
    // statement 2
}
if ($@) {
    warn "caught error: $@";
}

There are various modules that provide more traditional try-like functionality, such as Try::Tiny.
