Class to create a wrapper to pipe function calls.

import inspect


class Pipe:
    """
    Create a wrapper to pipe function calls with the given value.
    The functions could be: value's method, builtin or any
    function in the current module.

    Examples:
        print(254 | Pipe() | hex | str.upper)

        print(Pipe(254) | hex | str.upper)

        print((254 | Pipe() | hex).upper())

        print(Pipe(254).hex().upper())
