BIPLAN

Also, give fib(48) a try. Python will switch to bigint, but (https://github.com/gioblu/BIPLAN/blob/master/documentation/n...): BIPLAN supports only one numeric variable type that is by default int32_t So, fib(48) will overflow, and probably will return a negative number. Preferring to give the right answer over giving an answer fast is one of the design decisions Python made. There also is the unconventional choice to use a global array to store variables, leading to “BIPLAN supports a maximum amount of 116 global variables”. I don’t think changing that to make it growable will affect speed much, though.

BIPLAN: https://github.com/gioblu/BIPLAN is a programming language, which comes with its own virtual machine and its compiler. It is really simple and it is an early protototype, although benchmarking it looks astonishingly quicker than other interpreted programming languages like python. How can be 3 orders of magnitude quicker than python? O_O
