C++ : Polymorphic inheritance without vtable

Inheritance and Virtual Table are often used to create interface in C++ polymorphic class
What if ... there were another way to do this ?
easier, cleaner, faster and more reliable
This article explains how to use CRTP, [std::variant](https://en.cppreference.com/w/cpp/utility/variant and std::visit to increase code performance.

#
# Usage:
#   deno info --import-map ./import_map.json <your_deno_script>.ts | gawk -f deno_dependency_analyzer.awk
#
# Description:
#   This Gawk script parses the output from 'deno info', extracts dependencies along with their sizes,
#   converts all sizes to megabytes (MB), aggregates sizes by unique paths, and lists the top 10 largest
#   dependencies sorted by size in descending order.
