Eiffel vs. Julia vs. Lua vs. python-sql Comparison Chart

Eiffel is the most comprehensive approach to the construction of successful object-oriented software. You spend less on development, debugging, and maintenance. You get the bugs before they get you. You release quality products ahead of your competitors. Easier in every way, understanding, maintenance, reuse, and extension. Eiffel is the only approach that covers analysis, design, implementation, and maintenance in a single framework. Systems developed using Eiffel can be made portable across major industry platforms. Based on a small number of powerful ideas from computer science and software engineering. Products of all phases are recorded in a single document with multiple views. Exists to express the products of the Eiffel Method. Supports features not always available in competing technologies. Exception handling based on software specification (versus ad hoc try/catch). Widely recognized as simultaneously the simplest and most complete implementation of object-oriented concepts.

Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode with a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping. Lua has a deserved reputation for performance. To claim to be "as fast as Lua" is an aspiration of other scripting languages. Several benchmarks show Lua as the fastest language in the realm of interpreted scripting languages. Lua is fast not only in fine-tuned benchmark programs, but in real life too. Substantial fractions of large applications have been written in Lua.
