+I embarked on my programming journey with Fortran, a common initiation for many physicists. The ascent of NumPy and SciPy
+eventually piqued my interest, compelling me to explore Python. As my fascination with Python waned, I ventured into C++, only to find
+its lack of aesthetic appeal steering my curiosity towards Lisp and Haskell. Despite my reservations about certain aspects of
+these languages, the quintessence of the features I admire in them traces its origins to *APL*, i.e. to
