TinyScheme

What does /prague/ think of TinyScheme? It's a mostly complete R5RS interpreter, but without hygienic macros and syntax rules. It's painfully easy to embed into C or to extend with C, and is so small it can be shipped on anything, including micro-controllers with maybe a few hundred kilobytes of storage. It's also the most distributed version of Scheme, as it is the main scripting language for The GIMP, and was shipped to over 4 million computers with adware.

I think Lua is useless. Just use Ruby.
