Nevertheless, a number of compilers have subsequently been written. A number of extensions to the original "Befunge-93" specification also exist, including Funge-98, which extends the concept to an arbitrary number of dimensions and can be multithreaded, with multiple instruction pointers operating simultaneously on the same space. Befunge-extensions and variants are called Fungeoids or just Funges.
Similarly, in Befunge, there is no comment syntax: to embed documentation in the code, the programmer simply routes the control flow around the "comment" area, so that the text in that area is never executed.
