He talks about it in a blog post [1] and uses Steve Yegge's definition [2] of "code that writes code that writes code". Ioke is homoiconic and seems to contain fexprs (functions which allow you to pass it unevaluated code to be evaluated (or not) later, thus capturing dynamic scope), like Io, and unlike most modern lisps.

Here is the definition the creator has.

I imagine they are trying to create something that could take the roles of both low-level and high-level, like C++ and Lua in a gaming engine.

From wikipedia:

In functional programming, fold – also known variously as reduce, accumulate, aggregate, compress, or inject – refers to a family of higher-order functions that analyze a recursive data structure and through use of a given combining operation, recombine the results of recursively processing its constituent parts, building up a return value. Typically, a fold is presented with a combining function, a top node of a data structure, and possibly some default values to be used under certain conditions. The fold then proceeds to combine elements of the data structure's hierarchy, using the function in a systematic way.

I was trying to help out those asking about what Fold is. I guess it doesn't show well if the Wikipedia explanation is confusing!

The definition of folding in Wikipedia is not relevant to Ola Bini's usage of the term.

Thanks. I misunderstood both of them.
