Mixin class providing the tap method.

`tap(func, *args, **kwargs)`

Pass Self to func, call it, and return Self to continue chaining.

This method is very useful for debugging or passing the instance to other functions for side effects (debugging, IO operations, logging, etc.), without breaking the fluent method chaining.

The return type assume that func does not modify the instance, and that it returns None or any other value that is not used.

Parameters:

Name	Type	Description	Default
`func`	`Callable[Concatenate[Self, P], object]`	Function to apply to the instance for side effects.	required
`*args`	`P.args`	Positional arguments to pass to func.	`()`
`**kwargs`	`P.kwargs`	Keyword arguments to pass to func.	`{}`

Returns:

Name	Type	Description
`Self`	`Self`	The instance itself, unchanged.

Example

>>> from pyochain import Seq
>>> Seq((1, 2, 3, 4)).tap(print).last()
Seq(1, 2, 3, 4)
