Usual disclaimer: python-dev is for the development *of* python, not *with*. See python-list, etc. That said, def declares new functions or methods, so you can't put arbitrary expressions in there like type(f).__mul__ . You can usually assign to things like that though, but in this case you run

[Python-Dev] Function Operators

2010-07-18 Thread Christopher Olah
Dear python-dev, In mathematical notation, f*g = z->f(g(z)) and f^n = f*f*f... (n times). I often run into situations in python where such operators could result in cleaner code. Eventually, I decided to implement it myself and see how it worked in practice. However, my intuitive implementation [
