"Nabla" is based on the APL, an information processing description language designed in the 1960s to conveniently describe global operations on mathematical and pre-computing arrays, the PLA grammar was similar to that of natural language but did not use words, but many signs, each corresponding to a specific concept. In this language, the sign Nabla (∇) means that one wishes to enter or leave the mode of definition of a function.
