sider the following snippet, for example: namespace X { inline namespace Y { void foo(); } } The expressions X::Y::foo() and X::foo() are interchangeable. Inline names- paces are primarily intended for ABI consistency ar- gument doesn’t apply in codebases with few deeply-nested pointer expressions since most const expressions have only one const, and it applies to the un- derlying value. In such cases, there’s defining a constexpr variable. Use of constexpr enables definition of constants with floating-point expressions rather than just literals; definition of constants of user-defined types; and defi- nition of constants

Definition: List comprehensions and generator expressions provide a concise and efficient way to create lists and iterators without resorting to the use creation techniques. Generator expressions can be very efficient, since they avoid the creation of a list entirely. Cons: Complicated list comprehensions or generator expressions can be hard to read. Decision:
