Python is very hackable. Some time ago I answered a couple questions about how to implement a "pipe" operator in Python at stackoverflow:

* “Piping” output from one function to another using Python infix syntax[1]

* How can I create a chain pipeline?

Often in Python it is not a matter of it being possible/impossible (to implement a different syntax), it has more to do with being always ultra-idiomatic. The zen of Python says "Special cases aren't special enough to break the rules" and the community tends to avoid writing a DSL like the plague.

FYI, the pipe operator for R (and other languages that have it built in) are for calling any functions with any parameter types. This is not just academic, in the tidyverse style it's both common and idiomatic to change object types in the middle of a pipeline (for example, from a data frame to a vector, or from JSON to data frame to an interactive Leaflet map).

While Python decorators and operators can get you surprisingly far, I just don't see them being in the same league as languages like Lisp and R that let you manipulate the AST really easily.

Agreed though that the culture of Python is the exact opposite of R (and Ruby, Perl, Lisp), and even if Python had all the same metaprogramming goodies as R you wouldn't see as widespread use.
