 - Implementing a web left-right sweeping image gallery with HTML [iframe](iframe.md) instead of some overcomplicated [JavaScript](js.md) library. { Example stolen from [reactionary software](reactionary_software.md) website. ~drummyfish }
 - Supporting only [ASCII](ascii.md) (or something like [ISO 8859-1](iso88591.md)) instead of [Unicode](unicode.md), it is [good enough](good_enough.md).
 - Using a plain text flat file instead of a [database](database.md) system.
+- In [programming](programming.md) simply using identifier prefixes instead of [namespaces](namespace.md) which require another feature to be added to the language. This is done e.g. by [SDL](sdl.md) -- all functions from the library start with `SDL`, which prevents [collisions](collision.md) with user identifiers.
 - Using [markdown](markdown.md) for creating documents, as opposed to using office programs such as [Libreoffice](libreoffice.md).
 - Using a trivial [shell](shell.md) script for compiling your programs rather than a complex build system such as [CMake](cmake.md).
 - Using [ASCII art](ascii_art.md) instead of bitmap images.
