[over.literal] (original) (raw)

[Note 1:

Literal operators and literal operator templates are usually invoked implicitly through user-defined literals ([lex.ext]).

However, except for the constraints described above, they are ordinary namespace-scope functions and function templates.

In particular, they are looked up like ordinary functions and function templates and they follow the same overload resolution rules.

Also, they can be declared inline or constexpr, they can have internal, module, or external linkage, they can be called explicitly, their addresses can be taken, etc.
