In page APL (programming language):

"

APL uses a set of non-ASCII symbols, which are an extension of traditional arithmetic and algebraic notation. Having single character names for single instruction, multiple data (SIMD) vector functions is one way that APL enables compact formulation of algorithms for data transformation such as computing Conway's Game of Life in one line of code.[4] In nearly all versions of APL, it is theoretically possible to express any computable function in one expression, that is, in one line of code.[citation needed]
