Replace the strict/warnings boilerplate with a single `use v5.36` pragma, which enables strict, warnings, and subroutine signatures. Then convert manual `@_` unpacking to signatures, switch circumfix dereferencing to postfix syntax, and replace blessed hashrefs with Moo classes.

Moo is a lightweight object system with fast startup and a subset of Moose features, making it the preferred default for most applications. Use Moose only when you need its full metaprotocol, such as advanced introspection or meta-class manipulation.

Use Try::Tiny for reliable try/catch semantics on Perl 5.36, since plain eval/die has edge cases with $@ clobbering. On Perl 5.40 and later, the native try/catch syntax is available without external modules.

Two-argument open embeds the mode in the filename string, allowing shell metacharacters in user-controlled paths to trigger unintended behavior. Always use three-argument open with an explicit mode like `open my $fh, '<:encoding(UTF-8)', $path`, ideally combined with autodie.

Yes, subroutine signatures are stable in Perl 5.36 and enabled automatically by `use v5.36` without any experimental warnings. They provide automatic arity checking and support default values and slurpy parameters.

Declare dependencies in a cpanfile with version constraints, then use Carton to install them into a local directory. Run scripts with `carton exec -- perl bin/myapp` to ensure the pinned dependency set is used.
