They’re a convenient written form to approach an unfamiliar domain by dispelling myths, point out common pitfalls, show inconsistencies and subtleties.\n\u003e In a sense, Falsehood articles are a suite of wordy unit-tests covering extensive edge-cases provided by real-world usage.\n\n# General Myths\n\n  - Smalltalk is obsolete.\n  - Smalltalk is a programming language.\n  - It doesn't work for real-world development.\n  - All Smalltalk flavors are image-based.\n  - A Smalltalk Image cannot be bootstrapped.\n  - All Smalltalks includes UI classes.\n  - All implementations uses green threads.\n  - Smalltalk is not used in Big Data Science.\n  - You cannot use Smalltalk from command line.\n  - There are few libraries in the ecosystem.\n  - Most implementations do not support Full Closures.\n  - Most implementations do not support executable generation.\n  - There are no implementations supporting native widgets.\n  \n# Reflection Myths\n  \n  - Metaclasses are necessary to have a working Smalltalk.\n  - ClassDescription is necessary.\n  - Behavior is necessary.\n  - Subclassing Behavior has no use. \n  - You cannot add hidden behavior to a method.\n  - You can add it, but you need to recompile the method.\n  - It is impossible to avoid a hierarchy recompilation when an instance variable is added to a class.\n\n# VM Myths\n\n  - All Smalltalk bytecode sets are stack-based VM.\n  - All VM implementations uses bytecodes.\n\n# GC \u0026 Efficency Myths\n\n  - Smalltalk is less efficient than \"low-level\" languages.\n  - Smalltalk can't do \"real time.\"\n  - Garbage collection is less efficient than manual memory management.\n  - Garbage collection is really slow if you use complex data structures.\n\n# Acknowledgements\n\n- Eliot Miranda\n- Jecel Assumpcao Jr.\n- Reinout Heeck\n- Stephen Pope\n- Hernán Morales Durand\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhernanmd%2Ffalsehoods_smalltalk","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhernanmd%2Ffalsehoods_smalltalk","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhernanmd%2Ffalsehoods_smalltalk/lists"}
