A call to a literal operator (C++11 [over.literal]) written as a user-defined literal (C++11 [lit.ext]).
Represents a user-defined literal, e.g. "foo"_bar or 1.23_xyz. While this is semantically equivalent to a normal call, this AST node provides better information about the syntactic representation of the literal.
Since literal operators are never found by ADL and can only be declared at namespace scope, a user-defined literal is never dependent.
The kind of literal operator which is invoked.
