This module contains functions for generating string representations of Lua objects. It is inspired by Python's repr function. Usage. To use the module, first you ...
funcName: The function name. This parameter is required, and must be a string. args: The function arguments. This should be sequence table. The sequence items can be any Lua value, and will each be rendered using the [[#repr|]] function. This argument is optional. options: A table of options. The options are the same as for the repr function ...
Python : Prior to version 3.0, backticks were a synonym for the repr() function, which converts its argument to a string suitable for a programmer to view.

The read function accepts an expression from the user, and parses it into a data structure in memory. For instance, the user may enter the s-expression (+ 1 2 3), which is parsed into a linked list containing four data elements. The eval function takes this internal data structure and evaluates it. In Lisp, evaluating an s-expression beginning ...

In Python, functions are first-class objects that can be created and passed around dynamically. Python's limited support for anonymous functions is the lambda construct. An example is the anonymous function which squares its input, called with the argument of 5:
The memory layout of unions in Rust is undefined by default, [8] but a union with the #[repr(C)] attribute will be laid out in memory exactly like the equivalent union in C. [9] Reading the fields of a union can only be done within an unsafe function or block, as the compiler cannot guarantee that the data in the union will be valid for the ...
